| 摘 要： | 为研究强震动记录的破坏特性,对多条国内外常用的强震动记录的特性参数进行了对比分析.结果表明,强震动记录特性参数之间的相关件很小;PGA(PGV)和EPA(EPV)大小关系受震级和震中距影响较大;VSI较ASI能够更准确的评价强震动记录的破坏特性;与其它参数相比,强震动记录破坏强度参数(PD)同时考虑了地震加速度、时间和...

| Abstract: | To study the damage characteristics of strong motion records,this paper employed a number of strong motion events around the world,calculated and analyzed their characteristic parameters of the seismic wave.The results show that the correlation between these parameters is very small;The relationship of PGA（PGV） and EPA（EPV） is seriously effected by the magnitude and epicenter distance;VSI is a better parameter than ASI on evaluation of damage characteristics of strong motion records;Comparing with other parameters,destructiveness potential factor（PD） has considered the effect of the maximum ground acceleration,duration,and frequency spectrum.The influence of various parameters should be taken into account to assess the damage characteristics of strong motion records accurately. |
