Description

Technical Field

[0001] The present invention relates to the technical field of structural vibration reduction, and in particular to a design method, device, equipment, medium and product of a viscous damping wall. Background Art

[0002] Viscous Wall Dampers (VWD) are a new type of structural shock absorption and energy dissipation device, which includes an inner steel plate, an outer steel plate and a viscous liquid between the inner and outer steel plates. Under the action of earthquake or wind load, a relative velocity is generated between the upper and lower floors of the structure, and the inner and outer steel plates fixed to the upper and lower floors make relative reciprocating motions. The viscous material in the box produces shear deformation, and the internal friction generated by the flow of the viscous material consumes energy by doing work, thereby reducing the seismic response of the structure or the wind-induced dynamic response. VWD not only has a large damping force, good circulation performance, easy maintenance, and low maintenance costs, but it can also be hidden inside the wall of the engineering structure, which improves the seismic performance of the structure without affecting the beauty of the building.

[0003] At present, the finite element simulation of VWD only considers the damping effect produced by a single degree of freedom damping component or a single damping parameter, and the corresponding simulation results are not accurate enough, which will lead to inaccurate VWD design.

DETAILED DESCRIPTION

[0065] The technical scheme in the embodiment of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " herein, unless otherwise specified, generally indicates that the associated objects before and after are in an "or" relationship.

[0067] The following describes a design method, device, equipment, medium and product of a viscous damping wall provided by the present invention in conjunction with the accompanying drawings.

[0068] Figure 1 FIG. 1 is a flow chart of a design method for a viscous damping wall provided in an embodiment of the present invention. Figure 1 As shown, a design method for a viscous damping wall includes the following steps:

[0069] S101, construct a two-node model of the viscous damping wall and the first finite element model of the building frame structure.

[0070] The double-node model uses beam structures as nodes and each node includes at least one degree of freedom. The building frame structure includes at least two beam structures.

[0071] That is to say, the double-node model and the first finite element model are constructed respectively. The double-node model is obtained by modeling the upper and lower beam structures as nodes, and each node includes at least one degree of freedom direction. The beam structure can be a main beam, a secondary beam, a cross beam, an inclined beam, a truss beam, etc. The simplified version of the double-node model is as follows Figure 5 As shown, i and j are two nodes, L is , and The sum of is the total length of the viscous damping wall, and are the lengths of the upper and lower plastic hinge zones, is the effective strength of the viscous damping wall, A and B are the rigid ends of the upper and lower nodes of the viscous damping wall, respectively.

[0072] The first finite element model is a three-dimensional finite element model without VWD arrangement, such as Figure 2 As shown, it is specifically a three-dimensional finite element model of a building frame structure, which mainly includes vertical columns and horizontal beams, and may also include diagonal braces or other supporting structures, and may use steel, concrete, wood, composite materials, etc. The first finite element model is obtained by defining different parameters such as basic parameters, nodes, sections, materials, creation units, constraints, loads, etc. of the building frame structure. Specifically, a geometric model can be first constructed according to information such as the plane layout of the building frame structure, and then the type of finite element unit can be determined according to the material of the frame structure, etc. The constructed geometric model is divided into a unit network, and nodes are determined based on the unit network obtained by the division. Each node has its specific coordinates and degrees of freedom. Appropriate material properties are assigned to each finite element unit, and the connection relationship between units is determined. The constructed finite element model is solved by finite element analysis software to obtain the stress distribution, displacement response and deformation of the structure, etc. Finally, the first finite element model is analyzed and optimized to obtain the final first finite element model.

[0073] S102, analyzing the double-node model to determine an analytical expression for the damping coefficient and an analytical expression for the stiffness coefficient.

[0074] In this step, the shape function of each degree of freedom is obtained through the three-dimensional dimensions of the double-node model, and then the damping coefficient of the viscous damping wall and the damping coefficient of each degree of freedom, and the stiffness coefficient and the shape function of each degree of freedom are obtained according to the material properties of the viscous damping wall fluid, such as bending stiffness, distributed damping coefficient, etc.

[0075] S103, arranging the two-node model in the first finite element model according to the damping coefficient analytical expression and the stiffness coefficient analytical expression, and obtaining Figure 3 The second finite element model shown. The second finite element model is a double-node model of viscous damping wall set on the basis of the original first finite element model. Based on the second finite element model, the performance parameters of the viscous damping wall in the building frame structure can be determined. Figure 3 The double-node model between the two beam structures is as follows: Figure 4 shown.

[0076] In this step, the specific damping coefficient and stiffness coefficient are calculated based on the analytical expressions of the damping coefficient and the stiffness coefficient and the specific shape information of the two-node model in the first finite element model, and the calculated damping coefficient and stiffness coefficient are used to adjust the initial two-node model. The adjusted two-node model is then arranged in the first finite element model to obtain the second finite element model.

[0077] In the design method of the viscous damping wall provided by the embodiment of the present invention, the second finite element model not only considers the influence of the damping coefficient on the viscous resistance, but also considers the influence of the stiffness coefficient on the viscous resistance, so that the performance parameters of the viscous damping wall finally obtained are more accurate and effective.

[0078] In some embodiments of the present invention, arranging the two-node model in the first finite element model according to the damping coefficient analytical expression and the stiffness coefficient analytical expression includes:

[0079] The damping coefficient and the stiffness coefficient on each degree of freedom are respectively calculated according to the damping coefficient analytical expression and the stiffness coefficient analytical expression.

[0080] The viscous resistance force on each degree of freedom is calculated based on the damping coefficient and the stiffness coefficient, and the viscous resistance force includes a viscous damping force and a viscous restoring force.

[0081] The two-node model is arranged in the first finite element model according to the viscous resistance, and a second finite element model is obtained.

[0082] Specifically, the viscosity resistance is the viscous damping force and viscous restoring force sum.

[0083] in, , where is the viscous damping force, is the damping coefficient, is the velocity of viscous damping, and α is the damping exponent of viscous damping.

[0084] , where is the viscous restoring force, is the stiffness coefficient, is the displacement of the viscous damping, and β is the stiffness exponent of the viscous damping.

[0085] In this embodiment, various parameters of the building frame structure are first input into the finite element analysis software to create a first finite element model. Then, the double-node model of the viscous damping wall is added to the first finite element model to create a second finite element model. In this process, the analysis parameters of the viscous damping wall are further input through the finite element analysis software for analysis by the second finite element model to solve and obtain various responses of the second finite element model. The analysis parameters of the viscous damping wall here include the above-mentioned stiffness coefficient and damping coefficient. In the process of model solution, the viscous resistance will be obtained based on the stiffness coefficient and the damping coefficient. The viscous resistance needs to be considered in the process of solving various responses.

[0086] In some embodiments of the present invention, the damping coefficient is calculated according to the damping formula:

[0087] ;

[0088] The stiffness coefficient is calculated according to the stiffness formula:

[0089] ;

[0090] in, and are the lengths of the upper and lower plastic hinge zones of the element, is the effective length of the viscous damping wall, is the distributed damping coefficient per unit area, EI represents the bending stiffness, Calculate the geometric coefficients of freedom for the damping wall, is the shape function of the viscous damping wall. The shape function is the integral of the two degrees of freedom in the length direction after multiplying the functions of unit displacement in their respective directions. x is the integral variable of the viscous damping wall length. It means that the rth degree of freedom points to the sth degree of freedom.

[0091] In some embodiments of the present invention, the node includes 6 degrees of freedom, such as Figure 6 a to Figure 6 As shown in f, they are the up-and-down degree of freedom δ1 (i.e. the first degree of freedom), the left-and-right degree of freedom δ2 (i.e. the second degree of freedom), the front-and-back degree of freedom δ3 (i.e. the third degree of freedom), the yaw degree of freedom δ4 (i.e. the fourth degree of freedom), the pitch direction degree of freedom δ5 (i.e. the fifth degree of freedom) and the roll direction degree of freedom δ6 (i.e. the sixth degree of freedom).

[0092] The determining of the first relational expression between the damping coefficient and the viscous resistance and the second relational expression between the stiffness coefficient and the viscous resistance based on the double-node model comprises:

[0093] The damping coefficient and stiffness coefficient corresponding to each degree of freedom are calculated according to the unit shape function corresponding to each degree of freedom;

[0094] A first relational expression and a second relational expression are determined based on the damping coefficient and the stiffness coefficient.

[0095] In some embodiments of the present invention, the damping coefficient includes:

[0096] The first damping coefficient corresponding to the first degree of freedom :

[0097] ;

[0098] The second damping coefficient corresponding to the second degree of freedom :

[0099] ;

[0100] The third damping coefficient corresponding to the third degree of freedom :

[0101] ;

[0102] The fourth damping coefficient corresponding to the fourth degree of freedom :

[0103] ;

[0104] The fifth damping coefficient corresponding to the fifth degree of freedom :

[0105] ;

[0106] The sixth damping coefficient corresponding to the sixth degree of freedom :

[0107] ;

[0108] Where L is the total length of the viscous damping wall, is the height of the viscous damping wall, is the width of the viscous damping wall.

[0109] In some embodiments of the present invention, the stiffness coefficient includes:

[0110] The first stiffness coefficient corresponding to the first degree of freedom :

[0111] ;

[0112] The second stiffness coefficient corresponding to the second degree of freedom :

[0113] ;

[0114] The third stiffness coefficient corresponding to the third degree of freedom :

[0115]

[0116] The fourth stiffness coefficient corresponding to the fourth degree of freedom :

[0117] ;

[0118] The fifth stiffness coefficient corresponding to the fifth degree of freedom :

[0119] ;

[0120] The sixth stiffness coefficient corresponding to the sixth degree of freedom :

[0121] ;

[0122] Where A is the cross-sectional area of ​​the viscous damping wall, E is the elastic modulus of the viscous damping wall, is the area moment of inertia about the X-axis, is the area moment of inertia about the Z axis, is the area moment of inertia about the y-axis, and G is the torsional elastic modulus.

[0123] The design method of the viscous damping wall provided by the embodiment of the present invention takes into account the influence of the six degrees of freedom directions of each node on the viscous resistance, and objectively reflects the actual situation of the viscous damping wall by calculating the damping coefficient and stiffness coefficient of each degree of freedom.

[0124] In another embodiment of the present invention, after the second finite element model is obtained, an experimental comparison is also performed on the second finite element model. Specifically, the first finite element model (i.e., the finite element model without VWD), the finite element model considering only the damping coefficient (i.e., the damping model), and the second finite element model (i.e., the damping stiffness model) are experimentally compared, and the model performance is compared from the aspects of maximum displacement response, maximum acceleration, displacement angle, structural floor shear force, VWD hysteresis curve, etc.

[0125] like Figure 7 a to Figure 7As shown in d, under the action of earthquake vibration intensity of 0.05g, 0.1g, 0.2g, and 0.4g, the maximum displacement simulation value of each floor output by the damping stiffness model provided by the present invention is closer to the experimental data value than the damping model. Moreover, as the earthquake vibration intensity increases, the difference between the simulation value of the damping stiffness model and the experimental data value is larger and larger than the error between the simulation value of the damping stiffness model and the experimental data value, and the simulation value of the damping stiffness model is closer to the experimental data value. It can be seen that the role of stiffness in the VWD structure is becoming more and more obvious, and the damping stiffness model provided by the present invention is becoming more and more accurate.

[0126] like Figure 8 a to Figure 8 As shown in d in , under the action of earthquake vibration intensities of 0.05g, 0.1g, 0.2g and 0.4g, the maximum acceleration corresponding to each floor output by the damping stiffness model provided by the present invention is closer to the experimental data value than the damping model. It can be seen that by simulating using the damping stiffness model provided by the present invention, a more accurate simulation value of the maximum acceleration of the floor can be obtained.

[0127] like Fig. 9 a to Fig. 9 As shown in (d) in the figure, under the action of earthquake vibration intensities of 0.05g, 0.1g, 0.2g, and 0.4g, the simulated values ​​of the displacement angle between each floor output by the damping stiffness model are closer to the experimental data values ​​than the simulated values ​​output by the damping model.

[0128] like Fig.10 a to Fig.10 As shown in d in , under the action of earthquake vibration intensities of 0.05g, 0.1g, 0.2g, and 0.4g, the damping stiffness model and the damping model both correspond to shear values ​​on different floors. Although under the earthquake vibration intensities of 0.05g and 0.1g, the floor shear value of the damping stiffness model is just smaller than the floor shear value of the damping model, under the conditions of 0.2g and 0.4g, the difference between the two floor shear values ​​becomes larger. It can be seen that under the action of rare earthquakes, the floor shear value of the VWD structure installed is greater than the floor shear value of the non-VWD structure.

[0129] like Fig.11 a to Fig.11 As shown in d, they are test data, damping model simulation data, damping stiffness model simulation data and ANSYS simulation data (ANSYS simulation data is obtained through engineering simulation software ANSYS simulation). Comparing the test data with the damping model simulation data, and the test data with the damping stiffness model simulation data, the damping stiffness model simulation data is closer to the test data. In addition, by comparing the simulation results of a single VWD in ANSYS, the effectiveness of the damping stiffness model is verified.

[0130] In summary, compared with the previous single damping model, the damping stiffness model proposed in the present invention is accurate and effective. By using the damping stiffness model of the present invention to design a viscous damping wall, a more effective and accurate viscous damping wall can be obtained.

[0131] On the other hand, the present invention also provides a design device for a viscous damping wall, the device comprising:
