摘要
双柱大悬挑高架车站属于抗震不利结构。为了增强高架车站的抗震性能,结合具体工程实例,对岛式及侧式双柱大悬挑高架车站进行系统的抗震性能化分析。通过弹性及动力弹塑性计算可得出:结构在多遇地震下满足变形要求,罕遇地震下满足变形及延性设计要求,并且应采取有效的构造措施保证车站柱底及梁端的变形能力。所分析的项目具有一定的代表性,可为今后类似工程设计提供依据。
The double-column large cantilevered elevated station belongs to adverse seismic structure.In order to enhance the seismic performance of the elevated station,based on the concrete project examples,the performance-based seismic analysis is carried out on the island type and side type double-column large cantilevered elevated stations.Through the elastic and dynamic elastoplastic calculation,it can be concluded that the structure meets the requirements of deformation under frequent earthquakes and meets the requirements of deformation and ductility design under rare earthquakes,and effective structural measures should be taken to ensure the deformability of column bottom and beam end.The project analyzed is representative to some extent and can provide basis for similar engineering design in the future.
