摘要
从工程实例出发,介绍了建筑结构时程分析用地震波的选取,将记录到的地震波转换成时程分析输入用的地震波,同时也阐述了生成拟合反应谱的人工地震波的理论和方法。将强震地震波应用于工程实例,运用非线性有限元法对北京地区某高层钢筋混凝土框架抗震墙结构进行时程分析,阐明地震波选取与时程分析的重要性。
This paper introduces the selection of earthquake wave input for time-history analysis of structures based on engineering practice,the transformation of the earthquake wave recorded into the input for time-history analysis,and the theory and methods for the synthesis of simulated earthquake wave.Earthquake wave was applied to engineering projects,and nonlinear finite element program is used for the time-history analysis of reinforced concrete structures of a high-rise building in Beijing,so as to clarify the importance of the selection of earthquake wave input for time-history analysis of structures.
