Optimal design method for shear wall structure

Abstract

An optimal design method for a shear wall structure comprises the following steps: (1) establishing an Abaqus model of the shear wall structure; (2) building a shear wall structure test design comprehensive analysis platform, obtaining a numerical simulation calculation result of the shear wall structure, and further carrying out calculation; (3) taking the position distribution of the shear wall in the Abaqus model as a test design factor; and generating a design matrix for determining calculation item parameter selection and calculation times according to a specified test design algorithm; (4) performing sensitivity analysis on each set by applying a DOE method in the shear wall optimization design comprehensive analysis platform; (5) according to a sensitivity analysis result, eliminating factors with relatively small influence degree on a target result; (6) carrying out size optimization calculation on the remaining factors, and selecting a relatively optimal calculation scheme as a design result according to a target function; and (7) carrying out verification calculation. The effectiveness and reliability of optimization design of the shear wall structure are improved, and unattended intelligent optimization design is achieved.

Description

technical field [0001] The invention relates to the technical field of design of building structures, in particular to a method for optimal design of a shear wall structure. Background technique [0002] With the continuous increase and density of various complex buildings and super high-rise buildings in our country, in order to respond to social development requirements such as environmental protection, material saving, and carbon emission reduction, in addition to on-site construction control, the importance of building structure design is increasing. On the premise of meeting the requirements of the code, it is particularly important to obtain a structural design scheme with the best mechanical performance, the lowest cost, and the fewest materials. [0003] The design of the building structure is essentially a work aimed at meeting the specifications of the building structure, the requirements of the owner, and the building function. Its variables include the topologica...

Problems solved by technology

The traditional optimization design method has some common weaknesses: there is no clear standard and method to determine the optimization of the design; Not necessarily the best design solution, etc.

In the current building structure design, the new building structure system is continuously applied, the types and quantities of structural components are increasing, the force transmission path of the structure becomes more and more complicated, and it becomes more and more difficult to optimize the design work by relying on the designer's intuition and experience. Drawings without optimization happen from time to time, resulting in poor project economy and serious waste of materials, which do not meet the current social development requirements such as environmental protection, material saving, and carbon emission reduction.
