Problems solved by technology

The optimal design of energy-dissipating and shock-absorbing structures is often obtained by comparing and analyzing the calculation results of different schemes within a limited number of times, so there must be a lot of repetitive work
Especially for buildings with many floors and complex forms, such as high-rises and super high-rises, it takes a lot of time and energy to adopt the conventional design method of energy-dissipating and shock-absorbing structures, and the results obtained are also optimization within a limited range. Effectively realize the double maximization of safety benefit and economic effect

Embodiment 1

[0034] Embodiment 1: The method is mainly composed of three parts: a pre-processing part, a loop call optimization part, and a post-processing part. Among them, the cycle call optimization part is two parts before and after the optimization of the genetic algorithm and the anti-seismic checking calculation; the optimization of the genetic algorithm includes the inner cycle of the population.

[0035] (1) The pre-processing department, according to the current "Code for Seismic Design of Buildings" and other regulations, determines the seismic fortification target of the original structure; and conducts mode decomposition response spectrum method or time history analysis on the original structure; Determine the performance level of energy-dissipating and shock-absorbing structures.

Abstract

The invention relates to an energy dissipation and shock absorption optimization design method which is a joint optimization design method developed based on an MATLAB (matrix laboratory) genetic algorithm toolbox and an SAP2000 finite element program platform. The method includes a preprocessing part, a cycle call optimization part and a post-processing part; the cycle call optimization part is genetic algorithm optimization and anti-seismic checking calculation, and the preprocessing part is used for determining related parameters and codes and establishing an original model and initialized populations for the cycle call optimization part; the cycle call optimization part is realized through the genetic algorithm toolbox GATBX and SAP2000API function compilation, optimum individual are selected, and the post-processing part is used for extracting and processing optimization results to generate a corresponding calculation sheet. The characteristics of the genetic algorithm used in multi-objective problem optimization and a finite element program used in structural energy dissipation and shock absorption reinforcement analysis are integrated, and the method has bigger advantages than a conventional energy dissipation and shock absorption design method.

Description

technical field [0001] The object of the invention relates to a method for optimizing the design of an energy-dissipating and shock-absorbing structure by using a genetic algorithm, and belongs to the technical field of anti-seismic and energy-dissipating and shock-absorbing engineering structures. Background technique [0002] The traditional anti-seismic strengthening technology mainly relies on improving the anti-seismic performance of the structure itself, such as increasing the cross-sectional area of ​​the component, etc., and relying on the elastic-plastic deformation of the structure itself to dissipate the seismic energy. This is a passive anti-seismic countermeasure, without the ability of self-regulation and self-control. Although this "hard and hard" anti-seismic method has guaranteed to a certain extent that the house will not collapse during the earthquake, it has been proved that the damage to the house is very serious. As a kind of passive control technology...
