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
