人行荷载对大悬臂盖梁高架车站振动响应分析

Analysis of Vibration Response of Large Cantilever of Elevated Station by Pedestrian Load

文章以重庆轨道交通2号线某大悬臂盖梁独墩高架车站为研究对象,采用Midas/Civil建立整体模型,对高架车站结构进行人行荷载作用下的振动响应分析,对2个控制点的峰值加速度进行振动舒适度评价,结果表明,该大悬臂盖梁独墩高架车站的楼板满足由人行走引起的振动舒适度要求。

The paper takes an elevated station with cantilever of cap type and single beam on Chongqing rail transit line 2 as a research topic, using MIDAS/Civil to establish a holistic model to make an analysis on the elevated station structure of pedestrian load vibration response. An evaluation on vibration and comfort with two control points of peak acceleration is carried out. The results show that the large cantilever cap type and single beam for elevated station floor meet the vibration and comfort requirements induced by pedestrian load.
