摘要

本文详细阐述了合成人工地震波的全过程,为了和目标反应谱相符,在合成的过程中对人工地震波进行了零线调整和峰值调整,并对人工地震波的反应谱进行多次迭代。最后,采用Matlab编程软件编制人工地震波生成程序,合成某大桥在E1地震作用下和E2地震作用下的人工地震波,为接下来该大桥进行地震动力时程分析提供人工地震波输入。
This paper describes the synthesis of the whole process of artificial seismic waves. In order to be consistent with the target response spectrum, the zero line and the peak of artificial seismic waves are adjusted. At the same time, the fitting response spectrum of artificial seismic waves is performed iterative calculation. At last, an application of artificial seismic waves is programmed by Matlab software. By the application, artificial seismic waves of a long bridge are generated in the level of seismic action E1 and seismic action E2. Furthermore, the waves conduce to great value for dynamic time-history analysis of seismic.
