ABSTRACT

Two new, highly efficient single-parameter seismic intensity measures (IMs), one structure-specific and one structure-independent, are proposed for use on both bare and infilled reinforced concrete frames. The efficiency of these IMs has been evaluated along with the efficiency of several other IMs and seismic parameters over a group of 1568 bare and infilled frames. The ability of the investigated IMs to predict damage is evaluated on the basis of the correlation between IMs and the seismic damage, the dispersion of this correlation over the considered frames, its consistency across different seismic intensity levels, and its bias towards specific structural types.

摘要

提出了两种新的、高效的单参数地震强度测量 (IM)，一种是特定于结构的，一种是独立于结构的，用于裸露和填充钢筋混凝土框架。这些 IM 的效率已与其他几个 IM 的效率和地震参数一起在一组 1568 个裸框和填充框架上进行了评估。所研究的 IM 预测损伤的能力是根据 IM 与地震损伤之间的相关性、这种相关性在所考虑的框架上的分散性、其在不同地震强度级别上的一致性以及其对特定结构类型的偏向来评估的。
