Abstract

The magnitude, distance from the epicenter, effective duration, fault mechanism, and soil conditions influence the structural consequences of earthquakes. Variations in these characteristics cause structures to behave differently during seismic events. This study investigated the influence of some of these parameters on the seismic performance of moment-resistant frames. This was accomplished by simulating various well-known structures while accounting for panel zone and nonlinear component behaviour. Following that, these structures were exposed to several classified earthquake records. The distance from the fault, the soil type, and the fault mechanism were considered while classifying earthquakes. The findings revealed that the median value of story drift in strike-slip fault mechanism holds a greater level of significance when compared to reverse fault mechanism specifically in the context of far-field records. Also applying the near-field records has a greater impact on drifts in taller frames on stiff soils, and increasing the height of the frame has less impact on the fault mechanism effect on structures built on soft soils.

地震特性对钢抗弯框架抗震性能的影响

摘要

震级、距震中的距离、有效持续时间、断层机制和土壤条件都会影响地震的结构后果。这些特性的变化导致结构在地震事件期间表现不同。本研究调查了其中一些参数对抗弯框架抗震性能的影响。这是通过模拟各种众所周知的结构，同时考虑面板区域和非线性组件行为来实现的。此后，这些结构被暴露于几份机密的地震记录中。地震分类时考虑了距断层的距离、土壤类型和断层机制。研究结果表明，与逆断层机制相比，特别是在远场记录的背景下，走滑断层机制中的层漂移中值具有更大的意义。此外，应用近场记录对硬土上较高框架的漂移影响较大，而增加框架高度对软土上结构的断层机制效应影响较小。
