利用Midas/ Gen 软件,对车站整体进行建模,研究其在正常使用极限状态、极限承载力状态等静力工况下及地区同等级别、比地区高一等级抗震烈度地震波作用下结构响应。并结合现场实测车站钢屋盖应力与加速度数据,分别提出钢桁架应力及加速度黄色、橙色、红色3 个级别的预警阈值确定方法,设定了针对依托工程的三级预警阈值。可为同类型研究提供参考。
- Abstract:
-
The Midas/Gen software was used to model the station as a whole, and its structural response under static working conditions such as normal service limit state and ultimate bearing capacity state and that under seismic waves of the same level and one grade higher than the regional seismic intensity was studied. Combined with the on-site measured station steel roof stress and acceleration data, the determination method of three levels of early warning thresholds of steel truss stress and acceleration, i.e., yellow, orange and red, were proposed , and the three-level early warning threshold for the supporting project was set, which can provide reference for the same type of research.
