Description

Technical Field

[0001] This invention relates to the field of energy dissipation for outrigger trusses, and in particular to a lever-type secondary enlarged outrigger truss energy dissipation damping structure for preventing out-of-plane instability. Background Technology

[0002] With the development of society and economy and the acceleration of urbanization, the number of high-rise buildings, especially super high-rise buildings, is constantly increasing. In earthquake-prone countries, controlling the deformation of structures under seismic loads in high-intensity zones has always been a challenge in the design of super high-rise structures. At the same time, the increased structural height inevitably leads to increased displacement under horizontal loads and excessive bending moments in the upper shear walls or tubes. Traditional design solutions include increasing the cross-sectional dimensions of structural members, increasing the number of lateral force-resisting members, reducing design loads, and changing the structural form. A commonly used solution is to install outrigger trusses at appropriate locations within the structural height. Currently, the frame-core tube-outrigger truss structural system is widely used in super high-rise structures; therefore, research on the energy dissipation capacity of outrigger trusses has always been a hot topic in the industry.

[0003] Existing research on energy dissipation of outrigger trusses mainly focuses on two parts: First, research on energy dissipation of ordinary outrigger trusses. Zhao Xianzong et al., using the Shanghai Tower as a case study, conducted monotonic static loading tests on the connection areas of mega-column-outrigger-ring trusses and outrigger trusses-core tubes. Their research showed that outrigger trusses can effectively dissipate energy and coordinate the deformation of adjacent components. Chen Yiyi et al., building on the research of Zhao Xianzong et al., used various loading path schemes to test the connection area of ​​mega-column-outrigger-ring trusses. The tests showed that the final failure of the specimens occurred at the ends of the diagonal web members and the lower chord. Yan Peng et al., using actual engineering projects as research objects, conducted studies on the connection nodes between steel-concrete composite columns and outrigger trusses commonly used in super high-rise buildings. Large-scale model hysteretic loading tests showed that truss nodes have significant energy dissipation effects. Yang Qingshun et al. conducted 1:3 scaled-down tests, which showed that ordinary outrigger specimens experienced overall buckling of the web members and bending yielding of the chord members, exhibiting disadvantages such as rapid degradation of bearing capacity, poor ductility, and insufficient energy dissipation capacity. Secondly, in the study of energy-dissipating outrigger trusses, Yang Qingshun et al. replaced the web members of ordinary outrigger trusses with BRBs, and the test results showed that BRBs can effectively improve the seismic energy dissipation capacity of the structure. Zhou Y. et al.'s research results showed that using BRBs as web members of outrigger trusses can effectively improve the energy dissipation capacity of outrigger trusses under rare earthquakes. The research results of Ren Zhongcui et al. and Xing Lili et al. all showed that BRB outrigger trusses can fully utilize their energy dissipation capacity under horizontal loading.

[0004] For frame-core-outrigger truss structures, the energy dissipation capacity is limited due to constraints imposed by the outrigger truss's material properties and the relative deformation of the inner and outer tubes. To address these challenges, researchers have recently adopted the practice of incorporating energy dissipation and vibration reduction devices within the outrigger truss to absorb horizontal loads, including wind loads and seismic forces. Existing energy dissipation and vibration reduction devices often utilize horizontal shear deformation to dissipate energy. However, the deformation characteristics of super high-rise structures show that the proportion of bending deformation in the upper floors increases layer by layer, while the proportion of harmful shear deformation decreases layer by layer. Therefore, utilizing horizontal inter-story shear deformation for energy dissipation is limited. The frame-core-outrigger truss structure, on the other hand, uses the outrigger truss to coordinate the forces between the outer frame and the inner tube, thereby resisting overturning moments. The outrigger truss exhibits significant vertical deformation under horizontal loads, including wind loads and seismic forces, making it an ideal energy dissipation component.

[0005] The existing energy-dissipating outrigger trusses have the following drawbacks: Under horizontal loads (wind loads) and seismic action, the relative displacement or rotation between different structural components in the frame-core tube-outrigger truss structure system is relatively small, thus affecting the energy dissipation and vibration reduction effect of the energy dissipator. At the same time, existing energy dissipation devices occupy a large building area, affecting the efficiency of building space utilization. Summary of the Invention

[0006] The purpose of this invention is to provide a lever-type secondary expansion outrigger truss energy dissipation and damping structure for preventing out-of-plane instability. It aims to solve the technical problem that the relative displacement or rotation between different structural components in existing structural systems is small under horizontal loads, i.e., wind loads and seismic actions, which affects the energy dissipation and vibration reduction effect of the energy dissipator. It also aims to solve the technical problem that existing energy dissipation devices occupy a large building area, affecting the efficiency of building space utilization.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A lever-type, double-expansion, outboard truss energy dissipation and damping structure for preventing out-of-plane instability includes an inner cylinder structure and an outer frame structure, and further includes an energy dissipation outboard truss disposed between the two.

[0009] The outer frame structure includes outer frame columns, lower steel brackets, and upper steel brackets. The lower and upper steel brackets are vertically fixed to the inner side of the outer frame columns and are located in the same vertical plane as the energy-dissipating cantilever truss.

[0010] The energy-dissipating outrigger truss includes an outrigger truss and an energy-dissipating device for the outrigger truss. The outrigger truss is located in a vertical plane, perpendicular to the inner tube structure, and its inner end is fixedly connected to the outer wall of the inner tube structure. The energy-dissipating device is disposed between the outrigger truss and the outer frame structure.

[0011] The energy dissipation device and the outrigger truss are located in the same vertical plane, and include a primary amplification section, a secondary amplification section, and a rigid support section.

[0012] The primary amplification section includes a horizontal lever arm, the inner end of which is hinged to the outer end of the outrigger truss, and the outer end of which is hinged to the secondary amplification section.

[0013] The secondary amplification section is located outside the primary amplification section and includes an upper assembly and a lower assembly. The upper and lower assemblies have identical structures, each consisting of four equal-length rigid amplifier struts forming a rhomboid scissor brace and a horizontal damper. The ends of the rigid amplifier struts at each of the four corners of the rhomboid are hinged. The connection points of the two horizontally aligned rhomboid scissor braces are the inner and outer connection points, respectively. The horizontal damper is located within the rhomboid plane, with its two ends hinged to the inner and outer connection points. The connection points of the two vertically aligned rhomboid ends are the upper and lower connection points, respectively. The upper connection point of the upper assembly is hinged to the bottom of the upper steel bracket. The lower connection point of the upper assembly shares the same hinge point with the upper connection point of the lower assembly, i.e., the midpoint of the secondary amplification section. The lower connection point of the lower assembly is hinged to the top of the lower steel bracket.

[0014] The rigid support is located below the primary amplification unit and above the lower steel bracket. It includes a base and two rigid straight support rods of equal length. The base is fixedly connected to the top of the lower steel bracket. The upper ends of the two rigid straight support rods are hinged to the primary amplification unit through the same hinge point. The lower ends of the two rigid straight support rods are separated and respectively hinged to the inner and outer ends of the base. The base and the two rigid straight support rods form an isosceles triangle, making the rigid straight support rods serve as a stationary hinge support for the primary amplification device.

[0015] The outer end of the primary amplification section is hinged to the midpoint of the secondary amplification section.

[0016] The energy dissipation device also includes an out-of-plane instability prevention part, which is set at the same elevation as the horizontal lever arm. It includes an out-of-plane stabilizing baffle and a sliding layer. There are two out-of-plane stabilizing baffles. The outer end of the out-of-plane stabilizing baffle is fixedly connected to the inner side of the outer frame column. The inner end of the out-of-plane stabilizing baffle is clamped on the left and right sides of the midpoint of the secondary amplification part. The side of the out-of-plane stabilizing baffle facing the midpoint of the secondary amplification part is provided with a sliding layer. The side of the sliding layer facing the midpoint of the secondary amplification part is in contact with the side facing the midpoint of the secondary amplification part.

[0017] The horizontal damper is a viscous fluid damper, a shear-type metal damper, or a friction-type damper.

[0018] All hinged connections are perforated pin connections.

[0019] The outer end of the cantilever truss is provided with a cantilever truss ear plate, and the inner end of the primary enlargement part is hinged to the cantilever truss ear plate.

[0020] The bottom of the upper steel bracket is provided with an upper steel bracket ear plate, and the upper connection point of the upper half component is hinged to the upper steel bracket ear plate. The top of the lower steel bracket is provided with a lower steel bracket ear plate, and the lower connection point of the lower half component is hinged to the lower steel bracket ear plate.

[0021] The sliding layer is made of polytetrafluoroethylene.

[0022] The elevation of the lower connection point of the lower half component and the top hinged connection position of the lower steel bracket is equal to the elevation of the lower end of the rigid straight rod support and the hinged connection position of the base.

[0023] The elevation of the midpoint of the secondary amplification section is equal to the elevation of the upper end of the rigid straight rod support and the hinged connection position of the primary amplification section.

[0024] Compared with the prior art, the present invention has the following features and beneficial effects:

[0025] Features of this application:

[0026] To address the shortcomings of current structural damping outrigger devices, such as insignificant displacement amplification effects, and given that structures cannot tolerate large deformations or velocities, amplification devices are needed to amplify structural deformations or velocities to maximize the energy dissipation effect of dampers. This paper proposes a high-efficiency secondary amplification damper structure. The amplification effect of this invention allows the damper to generate larger displacements or velocities. The initial displacement is amplified by a displacement amplification lever, and then amplified a second time by a diamond-shaped scissor brace mechanism. This solves the problem of dampers not being able to fully utilize their energy dissipation effect under small displacement deformations. Through the combined movement of the primary amplification lever and the secondary diamond-shaped scissor brace mechanism, the structural deformation displacement or velocity is effectively amplified twice. This invention effectively improves the energy dissipation efficiency of dampers, significantly improving the performance of building structures under horizontal loads (wind loads) and seismic actions. Furthermore, this invention features simple construction, convenient installation, minimal impact on building function, and easy replacement, thus possessing broad application prospects.

[0027] Specific beneficial effects include:

[0028] I. In high-rise buildings, under the action of earthquake and wind loads, when the internal core tube undergoes bending deformation, the outer end of the outrigger truss moves up and down, generating vertical deformation. The primary amplification part uses the lever principle to amplify this vertical deformation difference and velocity difference. The secondary amplification part converts the vertical deformation after primary amplification into horizontal displacement after secondary amplification through the displacement of rigid connecting rods. The horizontal displacement after secondary amplification causes the viscous fluid damper to generate viscous damping force to dissipate energy, which more effectively dissipates earthquake energy and reduces the seismic response of the main structure.

[0029] Second, compared to the traditional combination of dampers and outrigger trusses, this device in super high-rise buildings can increase the energy dissipation of the dampers and significantly improve the additional damping ratio of the structure under earthquake and wind loads. This ensures structural safety while reducing the number of dampers, thus lowering project costs. Because the outrigger truss is connected to the outer frame via rigid connecting rods, forming a "finite stiffness reinforcement layer," the stiffness increase of this layer is relatively small. This prevents a sharp increase in internal forces and avoids abrupt stiffness changes that could create weak layers. Consequently, the structure exhibits a ductile yielding mechanism of "strong column-weak beam" and "strong shear-weak bending" under rare earthquake conditions.

[0030] 3. An out-of-plane stabilizing baffle is installed at the connection between the primary amplification section and the secondary amplification section. The out-of-plane stabilizing baffle, the corbel plate, and the rigid support work together to prevent lateral instability of the primary amplification section and the secondary amplification section.

[0031] Fourth, compared with the ordinary method of arranging vertical dampers at the end of the reinforced layer cantilever truss, the displacement amplification factor of the present invention is about 32 times that of the method of arranging vertical dampers at the end of the reinforced layer cantilever truss, resulting in better vibration reduction effect and higher working efficiency.

Detailed Implementation

[0049] See the examples. Figure 1-2 As shown, a lever-type secondary expansion outrigger truss energy dissipation damping structure for preventing out-of-plane instability includes an inner cylinder structure 4 and an outer frame structure, and also includes an energy dissipation outrigger truss disposed between the two.

[0050] The outer frame structure includes an outer frame column 1, a lower steel bracket 2, and an upper steel bracket 3. The lower steel bracket 2 and the upper steel bracket 3 are vertically fixed to the inner side of the outer frame column 1 and are located in the same vertical plane as the energy dissipation cantilever truss. The steel brackets are connected to the outer frame column by full penetration welding.

[0051] In this embodiment, the application is within a frame-core tube-outrigger truss structure system. In other embodiments, the inner and outer tube forms and the corbel forms are not limited to the forms described in this invention.

[0052] The energy-dissipating outrigger truss includes an outrigger truss 5 and an energy-dissipating device for the outrigger truss 5. The outrigger truss 5 is located in a vertical plane, perpendicular to the inner cylinder structure 4, and its inner end is fixedly connected to the outer wall of the inner cylinder structure 4. The energy-dissipating device is disposed between the outrigger truss 5 and the outer frame structure. In other embodiments, the arrangement of the outrigger truss is not limited to the form described in this invention.

[0053] The energy dissipation device and the outrigger truss 5 are located in the same vertical plane, including a primary amplification section 6, a secondary amplification section 7, and a rigid support section 8.

[0054] See Figure 1-2 As shown in Figures 5-6 and 13, the primary amplification section 6 includes a horizontal lever arm that rotates freely at the fulcrum, wherein its inner end is hinged to the outer end of the outrigger truss 5, and its outer end is hinged to the secondary amplification section 7.

[0055] See Figure 1-2 As shown in Figures 4 and 6-10, the secondary amplification section 7 is located outside the primary amplification section 6 and includes an upper component 7a and a lower component 7b. The upper component 7a and the lower component 7b have the same structure, each including four equal-length amplifier rigid straight rods 71 ​​forming a rhomboid scissor brace and a horizontal damper 72. The ends of the amplifier rigid straight rods 71 ​​at the four corners of the rhomboid scissor brace are all hinged. The horizontally aligned ends of the rhomboid are the inner and outer connection points, respectively. The horizontal damper 72 is located in the rhomboid plane, and its two ends are hinged to the inner and outer connection points. The vertically aligned ends of the rhomboid are the upper and lower connection points, respectively. The upper connection point of the upper component 7a is hinged to the bottom of the upper steel bracket 3. The lower connection point of the upper component 7a and the upper connection point of the lower component 7b are the same hinge point, namely the midpoint 73 of the secondary amplification section. The lower connection point of the lower component 7b is hinged to the top of the lower steel bracket 2.

[0056] The horizontal damper 72 is a viscous fluid damper, a shear-type metal damper, or a friction-type damper. In this invention, the bending deformation of the inner cylinder structure is amplified and converted into the axial deformation of the viscous fluid damper through a secondary amplification section. The viscous fluid damper is a velocity-dependent damper, dissipating energy through the velocity-deformation difference at both ends. As a velocity-dependent damper, the viscous fluid damper exhibits large deformation characteristics, capable of adapting to the large deformation requirements under rare and extremely rare earthquakes, thus forming an effective vibration reduction system. In other embodiments, the type of horizontal damper is not limited to those listed in this invention.

[0057] See Figure 1-2 As shown in Figures 11-12, the rigid support portion 8 is located below the primary amplification portion 6 and above the lower steel bracket 2. It includes a base 81 and two rigid straight support rods 82 of equal length. The base 81 is fixedly connected to the top of the lower steel bracket 2. In this embodiment, the base is a vertically arranged base plate ear plate, perpendicular to the lower steel bracket. The upper ends of the two rigid straight support rods 82 are hinged to the primary amplification portion 6 through the same hinge point. The lower ends of the two rigid straight support rods 82 are separate and respectively hinged to the inner and outer ends of the base 81. The base 81 and the two rigid straight support rods 82 form an isosceles triangle, making the rigid straight support rods 82 serve as a stationary hinge support for the primary amplification device.

[0058] See Figure 1-4 As shown, the energy dissipation device also includes an out-of-plane instability prevention part 9, which is set at the same elevation as the horizontal lever arm. This part includes an out-of-plane stabilizing baffle 91 and a sliding layer 92. Two out-of-plane stabilizing baffles 91 are provided. The outer ends of the out-of-plane stabilizing baffles 91 are fixedly connected to the inner side of the outer frame column 1, and the inner ends of the out-of-plane stabilizing baffles 91 are clamped on both sides of the midpoint 73 of the secondary amplification section. A sliding layer 92 is provided on the side of the out-of-plane stabilizing baffles 91 facing the midpoint 73 of the secondary amplification section, and the side of the sliding layer 92 facing the midpoint 73 of the secondary amplification section is in contact with the side facing the midpoint 73 of the secondary amplification section. The out-of-plane stabilizing baffles 91 are connected to the outer frame column by full penetration welding. The out-of-plane stabilizing baffles 91 only serve to constrain the out-of-plane instability of the amplification device. By using polytetrafluoroethylene (PTFE) material, the constraint effect on the truss plane of the amplification device is released, thereby ensuring the energy dissipation effect of the device. The sliding layer 92 is made of PTFE material. In other embodiments, the form of the out-of-plane stabilizing baffle is not limited to the form described in this invention.

[0059] See Figure 4-13As shown, all hinged connections are made using perforated pins 10, which can accommodate ear plates. The primary and secondary amplification sections of this invention are connected to the outer frame columns, outrigger trusses, and steel brackets of the main structure via pins, facilitating easy connections and simplifying the construction. Each part exhibits excellent in-plane and out-of-plane stability, enabling it to operate elastically under heavy earthquakes, ensuring that the bending deformation of the core tube during a heavy earthquake is converted into the axial deformation of the damper without loss.

[0060] See Figure 13 As shown, in this embodiment, the outer end of the outrigger truss 5 is provided with an outrigger truss ear plate 51, and the inner end of the primary enlargement part 6 is hinged to the outrigger truss ear plate 51.

[0061] See Figure 3-6 As shown, in this embodiment, the outer end of the primary amplification section 6 is hinged to the midpoint 73 of the secondary amplification section.

[0062] See Figure 10 As shown, the bottom of the upper steel bracket 3 is provided with an upper steel bracket lug plate 31, and the upper connection point of the upper half component 7a is hinged to the upper steel bracket lug plate 31. See [reference needed]. Figure 9 As shown, the lower steel bracket 2 is provided with a lower steel bracket ear plate 21 at its top, and the lower connection point of the lower half component 7b is hinged to the lower steel bracket ear plate 21.

[0063] See Figure 2 As shown, the elevation of the lower connection point of the lower half component 7b and the top hinged connection position of the lower steel bracket 2 is equal to the elevation of the lower end of the rigid straight rod support 82 and the hinged connection position of the base 81.

[0064] See Figure 2 , 6 As shown in Figure 11, the elevation of the midpoint 73 of the secondary amplification section is equal to the elevation of the upper end of the rigid straight rod support 82 and the hinged connection position of the primary amplification section 6, ensuring the energy dissipation effect.

[0065] In this embodiment, the working mechanism of the lever-type secondary enlarged outrigger truss energy dissipation damping structure for preventing out-of-plane instability is as follows:

[0066] See Figure 14-15 As shown, where: δ1 is the vertical deformation value of the outer end of the cantilever truss, that is, the difference in vertical deformation between the outer frame structure and the inner tube structure; r1 is the length value of the horizontal lever arm on the side adjacent to the inner tube structure; r2 is the length value of the horizontal lever arm on the side adjacent to the outer frame structure; δ2 is the axial deformation difference of the rhomboid scissor brace; δ3 is the axial deformation value of the horizontal damper; D1 is the axial length of the rhomboid scissor brace; L1 is the axial length of the horizontal damper.

[0067] From geometric analysis, we can obtain:

[0068] δ2=(r2 / r1)δ1(1-1)

[0069] δ3=(D1 / L1)δ2(1-2)

[0070] In summary, we can conclude that:

[0071] δ3=(D1 / L1)(r2 / r1)δ1(1-3)

[0072] As shown in the diagram, the rhomboid scissor braces are arranged in two sets, one above the other, and the final magnified effect is twice that of a single set.

[0073] Application examples: δ1=10mm; r1=500mm; r2=2000mm; D1=4000mm; L1=1000mm.

[0074] δ3=(D1 / L1)(r2 / r1)δ1=(4000 / 1000)×(2000 / 500)×10=160mm.

[0075] The magnification factor for a single set is 16 times; the magnification factor for a double set arranged symmetrically is 32 times.

[0076] See Figure 14-15 As shown, under seismic loading, a deformation difference δ1 is generated between the outer frame structure and the inner cylinder structure. Due to the amplification effect of the primary amplification section, the vertical deformation δ2=f1δ1 acting on the hinge point of the secondary amplification section, where the primary amplification coefficient f1=r2r1, and the vertical deformation δ2 is amplified again by the secondary amplification effect of the diamond scissor brace of the secondary amplification section, acting on the axial deformation δ3=f2δ2 of the viscous fluid damper, where the secondary amplification coefficient f2=D2 / L1. Therefore, the final amplification coefficient is f=f1f2. The larger the amplification coefficient f, the more energy the viscous fluid damper consumes, the smaller the seismic load on the main structure, and the more significant the energy consumption effect.
