Building structure design method based on multi-objective optimization

Abstract

A building structure design method based on multi-objective optimization comprises the following steps: (1) establishing an Abaqus model of a building structure; (2) building a multi-objective optimization design comprehensive analysis platform of the building structure, calling Abaqus software to obtain a numerical simulation calculation result of the building structure, and carrying out further calculation; (3) specifying an optimization algorithm in an Optimization module of the building structure multi-objective optimization design comprehensive analysis platform; (4) in the Optimization module of the building structure multi-objective optimization design comprehensive analysis platform, setting upper and lower limits for results including the cycle ratio, the interlayer displacement angle and the axial compression ratio to serve as constraint conditions of optimization calculation; (5) in the building structure multi-objective optimization design comprehensive analysis platform, generating an objective function containing the multiple objectives and the weight ratio of each objective; and (6) performing verification calculation in structural design software. The effectiveness and reliability of building structure optimization design are improved, and unattended intelligent optimization design is achieved.

Description

technical field [0001] The invention relates to the technical field of architectural structure design, in particular to a multi-objective optimization-based architectural structure design method. 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 ...

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.
