摘要
回顾了我国建筑结构抗震各阶段的设计方法,对89抗震规范以来结构性能化设计方法的发展进行了梳理分析,同时对现有规范的性能化方法提出了建议。对当前工程设计中若干重要问题,如反应谱、地震波、剪重比、刚重比、扭转位移比、层抗侧刚度、层抗剪承载力、薄弱层等进行了分析说明,并结合当前工程设计现状提出一些建议。
The Chinese seismic design methods for building structures in different stages were reviewed. Analysis on development of performance-based design methods since seismic design code of 1989 version was made and suggestions were provided for performanee-based design methods in current code. Analysis and illustration on some important problems in current engineering design were conducted, such as response spectrum, seismic wave, shear weight ratio, the ratio of stiffness to weight, torsional displacement ratio, story lateral stiffness, storey shear capacity, weak layer, etc. and some suggestions were provided for current engineering design conditions.
