[Introduction]In order to investigate the mechanism of dynamic elastic time response of structures in high intensity regions,an elastic dynamic time-history analysis is carried out for a central control building of a gas turbine generator plant.[Method]In this paper,three seismic waves were selected according to the current wave selection principle,and the elastodynamic time history analysis of the structure was carried out.[Result]The structural response result in the elastic dynamic time-history analysis is shown,which is compared with the structural response of the CQC mode decomposition response spectrum method.[Conclusion]Furthermore,according to the analysis result,the mechanism of structural dynamic response under high intensity region is investigated,the rationality and applicability of the elastic dynamic time history analysis are discussed,which provides reference for structural design and analysis of this kind of structure.
