［摘要］建筑结构时程分析基本包括:输入地震动、结构建模和输出结构响应三大部分。《建筑抗震设计规范》(GB 50011—2010)对结构抗震验算采用时程分析的适用范围、输入地震动加速度时程（地震波）的选择和检验做了较详细规定，对结构建模和输出结果的应用仅做了原则性规定。本文主体分两部分:第一部分介绍规范对时程分析法输入地震波选择与检验的原则及技术背景，即输入地震动准则；第二部分对如何解读结构弹性和弹塑性时程分析的输出结果，如：楼层剪力、弯矩、位移、结构损伤等数据的摘取和应用进行探讨，结合工程实例，评价输出结果的可信性和应用价值。专门探讨了地面峰值加速度GPA和有效峰值加速度EPA的定义，以及如何对地震波加速度数据进行调整。

Abstract:The time-history analysis of structures consists essentially three parts: selecting of earthquake acceleration records as input, modeling of structure, verifying and applying output data of structural response as well. Code for seismic design of buildings (GB 50011—2010) has issued for time-history analysis regulations regarding to the input earthquake, in terms of basic requirement, principle of selection and calibration of earthquake acceleration records in details, and requirements for modeling of structure and the output data. The paper consists of two main parts: part A introduces time-history analysis principle and technical method background for seismic wave selection and inspection in the code, namely the input ground motion criterion; part B discusses the verification and application of structural response given by the output data of linear and non-linear time history analyses, such as the shear, moment, drift of stories and the plastic damage of structure, etc. Some structures are given as examples to assess the reliability and reasonability of output data. Definitions and applications of ground peak acceleration GPA and effective peak acceleration EPA are given as well as how to adjust earthquake wave acceleration data.

Keywords:time-history analysis method; earthquake wave input; output result; storey shear; storey displacement
