| 摘 要： | 在基于性能的地震工程学中,采用地面运动强度参数(IM)来量化工程场地的地震活动性。一个理想的IM应该包含足够的关于地面运动特性的信息,可以将地面运动强度水平与结构地震反应水平有效地对应起来,还必须考虑到在地震工程学中,通过概率地震危险性分析进行地面运动危险性水平计算的可行性问题。因此,合理地选择IM,可以更加准确地预计在特定地震灾害环境下结构可能遭受到的最大破坏以及破坏规律,显著提高概率地震需求模型、工程需求参数危险性曲线以及易损性曲线等的精确性和计算效率。

| Abstract: | The ground motion intensity measure(IM) can be used to quantify regional seismic hazard for a given site and serve as an interface between the seismicity characterization and structural behavior assessment in performance-based earthquake engineering.Ideally,such a variable should contain sufficient information about the ground motion to serve as an accurate and efficient predictor of structural responses,and it should preferably be a variable for which the PSHA results are available.Maximum structural seism... |
