Abstract

This study is aimed at developing a new ground motion (GM) intensity measure (IM) based on: (i) the shape of the response spectrum and (ii) spectral acceleration at the fundamental elastic period of the structure, Sa(T1). The proposed GM-IM is developed mainly for short period reinforced concrete (RC) structures subjected to near-fault (NF) pulse-like GM records. The main parameter used in the development of the proposed IM is the ratio of peak ground acceleration (PGA) to peak ground velocity (PGV) of a ground motion record. The proposed IM displayed an improved performance among the other evaluated IMs.

近断层脉冲地震动短周期钢筋混凝土结构的地震动强度新测度

摘要

本研究旨在开发一种新的地震动 (GM) 强度测量 (IM),其基于:(i) 响应谱的形状和 (ii) 结构基本弹性周期的谱加速度 Sa(T1)。拟议的 GM-IM 主要针对受近断层 (NF) 脉冲式 GM 记录影响的短期钢筋混凝土 (RC) 结构而开发。拟议 IM 开发中使用的主要参数是地震动记录的峰值地面加速度 (PGA) 与峰值地面速度 (PGV) 之比。提议的 IM 在其他评估的 IM 中显示出改进的性能。
