地震动时程选择方法与影响因素研究综述

摘要

介绍了我国现行建筑抗震设计规范中所用地震动时程记录的选择方法,并探讨目前地震动选择方案的合理性.介绍了震级、震中距和持时等因素在地震动时程选择过程中产生的影响,根据其基本原理及应用实践指出了其优缺点,并对这些优缺点进行了简要分析.%This paper introduced selection methods of ground motion time history from seismic design code in China and discussed rationality of selection methods at present. According to basic rules and applying of ground motion time history selection they analyzed advantages and disadvantages of it. They also pointed out influence caused by magnitude, epicenter distance and time-delay during selection.
