Description

Technical Field

[0001] This invention relates to the technical field of civil engineering, and in particular to a method, system and storage medium for energy dissipation and vibration reduction structural design. Background Technology

[0002] With the rapid development of urbanization in my country, infrastructure and housing projects are still progressing at a high speed to meet people's daily production and living needs. However, my country is affected by the Circum-Pacific Seismic Belt and the Eurasian Seismic Belt, resulting in frequent earthquakes. The casualties and economic losses caused by high-intensity earthquakes have been extremely severe. Since the implementation of the "Regulations on Seismic Management of Construction Projects" in 2021, eight categories of buildings, including hospitals, schools, and nursing homes, have been explicitly required to adopt seismic isolation and damping technologies, further expanding the application scope of these technologies.

[0003] Traditional seismic design methods rely on increasing structural stiffness to resist earthquakes. This involves using elastic design to ensure minimal damage during minor earthquakes, structural measures to ensure repairability during moderate earthquakes, and limiting elastoplastic deformation to prevent collapse during major earthquakes. However, while increasing structural stiffness, this method also increases seismic load, resulting in insufficient safety redundancy and reduced building economy and practicality. Furthermore, while existing codes address energy dissipation and vibration reduction technologies, their implementation is hampered by numerous codes with varying requirements, significant subjective biases, and limitations imposed by regional differences, cost control, and technological capabilities. Consequently, implementation outcomes often deviate from the expected performance targets set by the codes. Therefore, a logically clear and easily implemented energy dissipation and vibration reduction structural design method is needed. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] Given the inconvenience of implementing the above-mentioned design methods for energy dissipation and vibration reduction structures, this invention is proposed.

[0006] Therefore, the technical problem solved by this invention is that existing energy dissipation and vibration reduction structures and design methods are greatly affected by human subjectivity, and the implementation results differ from the seismic performance targets expected by the standards, resulting in poor practicality.

[0007] To address the aforementioned technical problems, in a first aspect, this invention provides a method for designing energy dissipation and vibration reduction structures, applied to an energy dissipation and vibration reduction structure design system. The method includes: defining the seismic performance target of the structure; based on the seismic target and considering the influence of energy dissipation and vibration reduction components, and simultaneously designing according to minor earthquake elasticity and performance-based design for some components under moderate earthquake conditions, calculating the envelope value of the reinforcement results for minor earthquake elasticity and moderate earthquake design for some components, and generating a tangible model; performing model transformation on the tangible model and selecting appropriate seismic waves, and arranging energy dissipators; performing time history analysis based on the model transformation and the selected seismic waves; if the analysis results meet the expected target, then performing structural damage assessment; when the structural damage assessment reaches the expected seismic performance target, then designing the connection nodes of the energy dissipation components, thereby completing the analysis; if the analysis results do not meet the expected target, then adjusting the parameters or arrangement of the energy dissipation and vibration reduction components, and recalculating the analysis.

[0008] As a preferred embodiment of the energy dissipation and vibration reduction structural design method of the present invention, the performance-based design for moderate earthquakes is divided into two parts. The first part is: according to the code provisions, the performance level of key components is defined as normal section elastic and oblique section elastic, the performance level of ordinary vertical components and important horizontal components is defined as normal section non-yielding, and the performance level of ordinary horizontal components is defined as normal section non-yielding and oblique section non-yielding. The second part is: to preliminarily determine whether the structure meets the inter-story drift angle limit requirements under the design earthquake of the code provisions.

[0009] As a preferred embodiment of the energy dissipation and vibration reduction structural design method of the present invention, the calculated envelope value is realized based on the modal decomposition response spectrum method.

[0010] As a preferred embodiment of the energy dissipation and vibration reduction structural design method described in this invention, the model conversion should ensure that the mass, period, story shear force and other indicators of the structure before and after the conversion are similar, and the selected seismic wave should ensure that it meets the relevant requirements of the code.

[0011] As a preferred embodiment of the energy dissipation and vibration reduction structural design method of the present invention, the time history analysis is divided into elastic time history analysis for minor earthquakes, elastic / elastoplastic time history analysis for moderate earthquakes, and elastoplastic time history analysis for major earthquakes.

[0012] As a preferred embodiment of the energy dissipation and vibration reduction structural design method of the present invention, the structural damage judgment includes: extracting the plastic development data of the structure, judging the damage of the components in combination with the acceptable criteria of the components in the specification clauses, and then judging whether the structure has achieved the expected seismic performance target.

[0013] As a preferred embodiment of the energy dissipation and vibration reduction structure design method of the present invention, the design of the connection node of the energy dissipation component adopts a fully elastic design with 1.2 times the damping force corresponding to the design displacement or design velocity.

[0014] Secondly, an energy dissipation and vibration reduction structural design system is provided, the system comprising: a processor, a network module, a database, and a memory; wherein the processor and the memory communicate through the network module, and the processor reads and runs computer programs and specification clauses from the memory and the database.

[0015] The processor includes: a target selection module for defining the seismic performance target of the structure; a calculation module for calculating the envelope value based on the seismic performance target selected by the target selection module, combined with the code provisions in the database and the reinforcement results of minor earthquake elastic and moderate earthquake performance-based design of some components, and generating a tangible model; a model conversion module for converting the tangible model in the calculation module and selecting appropriate seismic waves and energy dissipators; and a time history analysis module for performing minor earthquake elastic time history analysis, moderate earthquake elastic / elastoplastic time history analysis, and major earthquake elastoplastic time history analysis based on the model conversion and selected seismic waves completed by the model conversion module. Analysis and Judgment Module: Includes an analysis and judgment module and a structural damage judgment module. The analysis and judgment module judges whether the analysis results of the time history analysis module meet the expected target. If they do not meet the target, it returns to the model conversion module to adjust the parameters of the energy dissipator or rearrange it for another time history analysis. If the analysis and judgment module judges that the target is met, the structural damage judgment module extracts the plastic development data of the structure and combines it with the code provisions in the database to judge whether the structure has achieved the expected seismic performance target. Design Module: When the structural damage judgment module judges that the target is met, it designs the connection nodes of the energy dissipation components.

[0016] Thirdly, a computer-readable storage medium is provided, wherein at least one instruction, at least one program, code set, or instruction set is stored in the storage medium, wherein the at least one instruction, the at least one program, the code set, or the instruction set is loaded and executed by a processor to implement the above-mentioned energy dissipation and vibration reduction structure design method.

[0017] The beneficial effects of this invention are as follows: The energy dissipation and vibration reduction structure design method, system, and storable medium provided in the embodiments of this application, combined with the seismic performance-based design method in the standard provisions, have been verified by engineering and meet the requirements of the standard. They effectively realize the classification and design of components according to their importance, enabling the structure to achieve the expected seismic performance target. While effectively ensuring the reliability of the structure, the project cost is not significantly increased. At the same time, since this invention relies on existing standard texts, it is not affected by the subjective influence of designers. It has clear logic, strong operability, and is easy for designers to understand and operate, and has the value of widespread application. Attached Figure Description

[0029] Figure 1 A block diagram of an energy dissipation and vibration reduction structural design system provided in an embodiment of this application is presented. The energy dissipation and vibration reduction structural design system in this embodiment can be a server with data storage, transmission, and processing functions, such as... Figure 1 As shown, the energy dissipation and vibration reduction structure design system 100 includes: a memory 110, a processor 120, a database 130, and a network module 140.

[0030] The memory 110, processor 120, database 130, and network module 140 are electrically connected directly or indirectly to enable data transmission or interaction.

[0036] Reference Figures 2-3 This is a schematic diagram of an energy dissipation and vibration reduction structural design method provided in this embodiment. The method steps defined in the relevant process flow are applied to the energy dissipation and vibration reduction structural design system 100, and can be implemented by the processor 120. Figures 2-3 It can be seen that the method includes the following steps S1 to S6:

[0037] In the following scheme, the "Code for Seismic Design of Buildings" is abbreviated as "Code", the "Guidelines for Seismic Technology Based on Maintaining the Normal Use Function of Buildings" (draft for approval) is abbreviated as "Guidelines", and the "Regulations on Seismic Management of Construction Projects" is abbreviated as "Regulations".

[0038] S1: Define the seismic performance targets of the structure.

[0039] The seismic performance targets of a structure include the following aspects: structural components remain basically intact or suffer minor damage under the design earthquake action, and suffer slight or moderate damage under rare earthquake action; energy dissipation and damping components function normally under the design earthquake action and rare earthquake action; non-structural components of the building remain basically intact under the design earthquake action, and suffer slight damage under rare earthquake action.

[0040] S2: Based on the seismic performance target and considering the influence of energy dissipation and damping components, and in accordance with the elastic design for minor earthquakes and the performance-based design of some components for moderate earthquakes, calculate the envelope value of the reinforcement results for the elastic design for minor earthquakes and the performance-based design of some components for moderate earthquakes, and generate a shaped model.

[0041] Where: Reference Figure 3 The performance-based design for moderate earthquakes consists of two parts. The first part defines the performance levels of key components as elastic in normal sections and elastic in oblique sections, and the performance levels of ordinary vertical components and important horizontal components as non-yielding in normal sections, and the performance levels of ordinary horizontal components as non-yielding in normal sections and non-yielding in oblique sections, according to the code provisions. The second part preliminarily determines whether the structure meets the inter-story drift angle limit requirements under the design earthquake specified in the code provisions, and the design results after calculating the envelope value should meet the code requirements. More specifically, to achieve the requirement of the "Regulations" to "ensure that the structure can meet the normal use requirements when an earthquake of design intensity occurs in this region":

[0042] ① Adopting the method of Appendix M of the Code for Seismic Design of Buildings and Article 4.2 of the Guidelines, the performance level of key components is defined as normal section elasticity and oblique section elasticity (both corresponding to Article M.1.2-2 of the Code for Seismic Design of Buildings), the performance level of ordinary vertical components and important horizontal components is defined as normal section non-yielding (corresponding to Article M.1.2-3 of the Code for Seismic Design of Buildings) and oblique section elasticity (corresponding to Article M.1.2-2 of the Code for Seismic Design of Buildings), and the performance level of ordinary horizontal components is defined as normal section non-yielding and oblique section non-yielding (corresponding to Article 4.2.4 of the Guidelines).

[0043] The following are some of the provisions in Appendix M of the Seismic Design Code:

[0044] Table M.1.1 Examples of bearing capacity reference indicators for structural components to meet seismic performance requirements

[0045]

[0046]

[0047] The calculation formula for M.1.2.2 is as follows: When verifying the bearing capacity of structural members based on the design value adjusted without considering seismic effects, the basic combination that does not take into account wind load effects should be used, and the following formula should be used for verification:

[0048] γ G S GE +γ E S EK (I, ζ)≤R / γ RE

[0049] Where: I represents the design intensity ground motion or rare ground motion, and the seismic isolation structure includes horizontal damping effects; ζ represents the stiffness reduction considering the plasticity of some secondary components or the additional damping effects of the energy dissipation and damping structure. This formula characterizes the concept of "elasticity".

[0050] The calculation formula for M.1.2.3 is as follows: When verifying the bearing capacity of structural members according to standard values, a standard combination of seismic action effects that does not take into account wind load effects should be used, and the calculation should be performed according to the following formula:

[0051] S GE +S EK (I, ζ)≤R k

[0052] Where: I represents the design ground motion or rare ground motion, and the seismic isolation structure includes horizontal damping effects; ζ represents the damping effects of considering the stiffness reduction of some secondary components entering the plastic state or the additional damping effects of the energy dissipation and damping structure; R k This represents the bearing capacity calculated based on the standard value of material strength. This formula represents the concept of "non-yielding".

[0053] Article 4.2 of the Guidelines states: The load-bearing capacity of structural components of buildings in normal use during an earthquake should be verified according to the design seismic action. That is, buildings in normal use during an earthquake should be able to continue to be used without repair when subjected to an earthquake of the same intensity as the seismic fortification intensity of the region. Therefore, the load-bearing capacity of their structural components should be verified according to the design seismic action.

[0054] Article 4.2.4 of the Guidelines states: The shear bearing capacity of ordinary horizontal concrete members of buildings in normal use under earthquake conditions shall conform to the following formula:

[0055] S GE +S Eh +0.4S Ev ≤R k

[0056] S GE +0.4S Eh +S Ev ≤R k

[0057] Wherein: S Eh The effect representing the standard value of horizontal seismic action should be multiplied by the corresponding amplification or adjustment factor; S Ev The effect representing the standard value of vertical seismic action should be multiplied by the corresponding amplification or adjustment factor. R k This represents the standard value of the bearing capacity of a typical horizontal structural member, calculated based on the standard value of material strength. This formula represents the concept of "non-yielding".

[0058] The normal section bearing capacity of ordinary horizontal concrete members, the shear bearing capacity and the normal section bearing capacity of ordinary horizontal steel members of buildings in normal use under earthquake design conditions shall conform to the following formula:

[0059] S GE +S EhK +0.4S EvK ≤R k *

[0060] SGE +0.4S EhK +S EvK ≤R k *

[0061] Wherein: S EhK This represents the effect of the standard value of horizontal seismic action, without considering amplification or adjustment factors; S EvK This represents the effect of the standard value of vertical seismic action, without considering amplification or adjustment factors; R k * This formula represents the standard value of the bearing capacity of ordinary horizontal structural members, calculated based on the standard value of material strength. For reinforced concrete beam supports or node edge sections, the standard value of the steel reinforcement strength can be increased by 25% during calculation. For steel beam supports or node edge sections, the standard value of the steel yield strength can be increased by 25% during calculation. This formula represents the concept of "considering the material's superior non-yielding strength".

[0062] ② Make a preliminary judgment on whether the structure meets the inter-story drift angle limit requirements under the design earthquake specified in Articles 4.3.1 or 4.3.2 of the Guidelines.

[0063] The selected provisions of the Guidelines, 4.3.1 and 4.3.2, are as follows:

[0064] Table 4.3.1 Limits of Elastoplastic Inter-story Shift Angles for Class I Buildings under Design Earthquake and Rare Earthquakes

[0065]

[0066] Table 4.3.2 Limits of Elastoplastic Inter-story Float for Class II Buildings under Design Earthquake and Rare Earthquakes

[0067]

[0068]

[0069] The envelope value is calculated based on the modal decomposition response spectrum method.

[0070] S3: Perform model conversion on the tangible model and select appropriate seismic waves, and arrange energy dissipators.

[0071] Energy dissipation and vibration reduction structures have higher requirements than conventional structures. They generally require seismic-specific review, comparative analysis of multiple mechanical models, and supplementary time history analysis. Model conversion should ensure that the mass, period, story shear force, and other indicators of the structure before and after conversion are close, and wave selection should ensure that it meets the relevant requirements of the code.

[0072] S4: Time history analysis based on model transformation and selected seismic waves.

[0073] Reference Figure 3As shown, time history analysis is divided into elastic time history analysis for minor earthquakes, elastic / elastoplastic time history analysis for moderate earthquakes, and elastoplastic time history analysis for major earthquakes. Specifically: (1) Elastic time history analysis for minor earthquakes: Based on the finite element model that has passed model transformation and seismic wave verification, the elastic time history analysis method is used to solve the response of the structure under frequent earthquakes. The modal analysis adopts the Ritz vector method, and the time history analysis adopts the FNA algorithm to determine whether the main structure and energy dissipation and damping components meet the expected performance targets under minor earthquakes; (2) Elastic / elastoplastic time history analysis for moderate earthquakes: The response solution method of the structure under the design earthquake can be... The structure is judged based on the state of elastic-plasticity. When the degree of plastic development of the structure is relatively light and the impact of the hinge on the whole is not obvious, the elastic time history analysis method can be used. Otherwise, the elastic-plastic time history analysis method should be used. The elastic time history analysis only needs to modify the peak acceleration based on the model of frequent earthquakes. When the elastic-plastic time history analysis method is used, the actual reinforcement of the structure should be imported, and the plastic hinge property of the component should be given to consider the plastic development of the component. The nonlinear direct integration algorithm is used. (3) Elastic-plastic time history analysis of major earthquakes: The elastic-plastic time history analysis method is used to solve the response of the structure under rare earthquakes.

[0074] If the time history analysis results do not meet the expected goals, return to S3, adjust the parameters or arrangement of the energy dissipation damper, and recalculate and analyze.

[0075] S5: If the analysis results meet the expected goals, then proceed with the structural damage assessment.

[0076] When assessing structural damage, the plastic development data of the structure is extracted, and the damage of the components is judged in conjunction with the acceptable criteria for components in the American standard ASCE 41-13 or FEMA 273, thereby determining whether the structure has achieved the expected seismic performance target.

[0077] S6: When the structural damage assessment reaches the expected seismic performance target, the connection nodes of the energy dissipation components are designed, and the analysis is then completed.

[0078] The design of the connection nodes of the energy dissipation components adopts a fully elastic design with 1.2 times the damping force corresponding to the design displacement or design velocity.

[0079] Reference Figure 4 Based on the same inventive concept described above, the processor 120 includes: a target selection module 121, a calculation module 122, a model conversion module 123, a time history analysis module 124, a judgment module 125, and a design module 126.

[0080] Target selection module 121: Used to define the seismic performance targets of the structure;

[0081] Calculation module 122: Based on the seismic performance target selected by the target selection module 121, and combined with the code clauses of 130 in the database and the reinforcement results of the elastic design under minor earthquakes and the performance-based design of some components under moderate earthquakes, the envelope value is calculated and a shaped model is generated. It can be operated using general structural design software PKPM or YJK.

[0082] Model conversion module 123: Converts the tangible model in calculation module 122 and selects appropriate seismic waves and energy dissipators;

[0083] Time history analysis module 124: Based on the model conversion completed by model conversion module 123 and the selected seismic waves, it performs elastic time history analysis of minor earthquakes, elastic / elastoplastic time history analysis of moderate earthquakes and elastoplastic time history analysis of major earthquakes. It can be implemented using general finite element analysis software such as SAP 2000, ETABS, or MIDAS GEN.

[0084] Judgment Module 125: Includes Analysis Judgment Module 125-1 and Structural Damage Judgment Module 125-2. Analysis Judgment Module 125-1 judges whether the calculation results of Time History Analysis Module 124 meet the expected target. If they do not meet the target, it returns to Model Conversion Module 123 to adjust the parameters of the energy dissipator or rearrange it and then perform time history analysis again. If Analysis Judgment Module 125-1 judges that it meets the target, Structural Damage Judgment Module 125-2 extracts the plastic development data of the structure and combines it with the code provisions in Database 130 to judge whether the structure has achieved the expected seismic performance target.

[0085] Design Module 126: When the structural damage judgment module 125-2 determines that the condition is met, design the connection node of the energy dissipation component.
