建筑结构设计中抗震性能化设计要点探讨

Discussion on Key Points of Performance-Based Seismic Design in Building Structure Design

结构抗震性能优化设计建立在概念设计的基础上,是一种全新的抗震设计理念。目前,不同国家在抗震设计方面,常采用静力法与反应谱法,按照弹性设计方式计算结构在地震作用下的变化。论文阐述了建筑结构抗震性能化设计概念的提出过程,介绍了建筑结构性能水准、性能目标等概念,并提出提高建筑抗震性能的途径等,以供参考。

Structural seismic performance optimization design is based on conceptual design,which is a new concept of seismic design.At present,in the aspect of seismic design in different countries,the static method and response spectrum method are often used to calculate the change of structure under earthquake action according to the elastic design method.This paper expounds the process of the concept of performance-based seismic design of building structures,introduces the concepts of performance level and performance target of building structures,and puts forward the ways to improve the seismic performance of buildings for reference.
