摘要
介绍了结构地震反应分析中的地震反应谱、设计反应谱等三种反应谱理论,并阐述了他们之间的相互联系和功能区别,论述了几种多自由度体系线性动力反应分析方法,为工程抗震设计提供了便捷、有效地分析手段。
Five response spectrum theories in structural seismic response analysis such as earthquake response spectrum, design response spectrum and so on are introduced. Interconnection and functional differences of them are analyzed; at the same time several linear dynamic response analysis methods of multiple-degree of freedom system is introduced in order to provide references for seismic design.
