Several Theoretical Problems in Seismic Design of Structure Based on Reliability Theory

本文对基于概率可靠度进行结构抗震设计的若干理论问题进行了探讨，包括：结构抗震设计 的目的与目标、结构抗震设计原则、结构抗震设计标准、地震作用的统计分析以及基于概率可靠度的 结构抗震设计方法，对其中有些问题作者提出了建议或设想，有的问题还有待研究解决。本文的思想 可供制订我国２０００年结构抗震设计模式规范和今后修订我国建筑抗震设计规范参考。

The problems in seismic design of structures based on reliability theory are discussed in this paper. These problems include the aim and objective of seismic design, principles and standards of seismic design, statistics of seismic effects, and the seismic design approach of structures based on reliability theory. The solutions of some of the problems are suggested by the author though some of them still remain to be unsolved for further study. The ideas proposed in this paper may probably be adopted for revision of the national code for seismic design of buildings.
