摘要
输入地震波的合理选择是影响结构时程分析结果可信度的重要因素。已有的最优双指标选波方案没有考虑地震动的持时和能量分布的影响。文中考虑地震动持时这一影响结构弹塑性反应的重要因素,以抗震结构的能量反应规律为基础讨论输入地震波选择问题,建议以地震动弹性总输入能反应作为补充指标的选波方案。
What types of earthquake waves should be chosen as input motion in time -history analysis, it is an important influence factor. Duration and energy distribution of the earthquake waves do not be considered in current methods of selecting earthquake waves. In this paper some methods of the selecling earthquake waves are discussed based on energy responses so that the influence factor of duration and energy distribution can be taken into account. The method of the selecting earthquake waves for using the total elastic input energy of earthquake as complementary factor is proposed.
