ABSTRACT

Analysis of alatticed spherical shell is carried out by using the scaled and spectrum-matched records. The seed records for scaling and spectrum matching are selected, so their ground motion intensity measures are consistent with chosen targets. The analysis results indicate that the use of the spectrum-matched records leads to the coefficient of variation (COV) values of the load effects to be similar or smaller than the lowest COV values obtained by using the records scaled to the target ground motion intensity measure. Use of the spectrum-matched records for this structural type is preferred for some design checking situations.

使用频谱匹配与比例记录来评估格子壳的地震响应

摘要

使用比例尺和光谱匹配的记录对网格球壳进行分析。选择用于缩放和频谱匹配的种子记录，因此它们的地震动强度测量值与所选目标一致。分析结果表明，频谱匹配记录的使用导致载荷效应的变异系数（COV）值接近或小于使用缩放到目标地震动强度测量的记录获得的最低COV值. 对于某些设计检查情况，首选使用这种结构类型的频谱匹配记录。
