摘要:
针对“站桥合一”的大型综合交通枢纽工程，通过建立有限元模型对其进行模态分析，研究在人致振动作用下候车厅楼板以及大跨度悬挑商业夹层结构的振动响应。以南昌西站、南京南站的站房结构为例，分别在有限元模型竖向阵型最大点施加人行荷载，在南昌西站不同区域的25 m跨中、18 m跨中、悬挑商业夹层处，在南京南站跨中楼板的不同区域(正线区域、正常区域)，研究同频率不同相位作用下和同频率同相位作用下人行荷载作用的振动响应。研究结果表明，人致振动同步调作用响应较大不可忽略，大跨度商业夹层处的振动响应比楼板响应大。
Abstracts:
A finite element model is established for a modal analysis of the large-scale integrated transport hub project which is a stationbridge unity , in order to study the vibration response of the waiting floor and the large span cantilever structure under the action of human induced vibration. Firstly, taking the station structure of Nanchang West Railway Station and Nanjing South Station as the examples, the maximum load of the vertical formation model is applied in the finite element model respectively. In different areas of Nanchang West Railway Station, including the 25m span, 18m span and the cantilever commercial interlayer, and in different areas of Nanjing South Station, the vibration response to the people loading in different phases of the same frequency, and that in the same phases of the same frequency are studied. The results show that the response of the human induced vibration can not be neglected, the vibration response at the larger span, like the commercial interlayer is also larger.
