从一个异于传统研究方法的角度出发,利用最近发展的地震动 3D 瞬态参数分析理论,有选择的研究了有关近场地震动记录的3D 瞬态特征;通过对典型近场地震动作用下结构模型的算例分析,探讨了速度脉冲型地震动与结构延性需求之间的关系,指出结构坏固然与地震动的反复作用有关,但对于大多数结构的关键破坏起控制作用的却可以归因于近场地震动的脉冲特性,这对认识结构破坏的根本原因具有重要意义。

近场地震动
1.
In this paper,Kanai-Tajimi model and He-Agrawal velocity pulse model are selected to conduct the nonlinear numerical simula- tion of several typical near-filed records,and many near-field ground motions are obtained by adjusting the ratio of random broadband com- ponent and pulse component.
选用宽频远场地震Kanai-Tajimi模型与He-Agrawal近场脉冲地震速度脉冲模型,对现有的典型近场地震记录进行非线性数值拟合,调整其脉冲分量与宽频分量的比值,得到不同脉冲分量的地震波;文中以一幢8层基础隔震结构为研究对象,分析了合成近场地震波下基础隔震结构的水平及转动动力响应,结果表明含有脉冲分量的近场地震动比远场地震动破坏力更大;基础隔震体系能有效地减小上部结构在近场地震动中的响应。
