轻轨铁路站桥整体结构的结构设计与抗震分析
|
摘要
本文结合地处高烈度地震区的天津轻轨工程,对轻轨铁路车站建筑与高架桥梁进行了整体设计与抗震分析。在结构设计中,首次将轻轨铁路的车站建筑与高架桥梁设计成为一个整体框架结构;在抗震分析中,分别按照不同的规范反应谱法和时程分析法对站桥整体结构进行全面分析。研究结果表明,轻轨铁路站桥整体结构的结构设计概念明确、优点明显,可避免建筑与桥梁之间的地震碰撞;按照规范反应谱法设计的站桥整体结构的抗震安全性存在不足,设计中必须按照工程建设场地地震危险性评价所给出的地震动参数对站桥整体结构进行时程分析,才能确保轻轨铁路的抗震安全性。
In this paper, associated with Tianjin Light Railway located at the area with high seismic intensity, the structural design and seismic analysis for the integral station-bridge structure constructed by the station building and the elevated bridge in light railway is performed. In the structural design, the station building and the elevated bridge of the light railway are designed as an integral frame structure firstly. In the seismic analysis, a overall analysis for the integral station-bridge structure is carried out according to the of the response spectrum and the time-history analysis methods respectively. The investigated results show that there are a clear concept and a remarkable advantage in the structural design for the integral station-bridge structure, which may avoid the seismic pounding between the building and the bridge. The seismic safety of the integral station-bridge structure designed according to the specified response spectrums in design codes is lower, and the time-history analysis must be carried out in design based on the parameters of earthquake motion provided by the seismic risk evaluation of engineering construction site, which will guarantee the seismic safety of the light railway.
