不同布索方式的正交梁系结构在车站雨棚中的应用
|
摘要
大跨度无站台柱雨棚设计是火车站建设的一个重点,它要求柱距大、跨度大.在各种大跨结构体系中如双层网架、柱面网壳、弦支网壳、张弦梁、实腹拱、拱形桁架、悬索、膜结构等,正交梁系结构由于其结构简洁、受力合理等优点而被广泛应用.论文对不同布索方式的正交梁系结构在车站雨棚中的应用进行了研究,探讨了不同布索方案对结构静、动力性能的影响,分析了结构的特征值屈曲和非线性屈曲,并采用弹性时程分析法比较了各方案抗震性能.研究结果表明合理的布索方案能有效改善正交梁系结构的承载力和抗震性能.
Design of long-span canopy without platform column is a key point in the construction of railway station and it requires big column spacing and large span.Among different large-span structural systems,such as double-layer grid structure,single-layer cylindrical lattice shell,suspended dome,beam string structure,solid-spandrel arch,orthogonal beam structure,arch truss,suspended cable structure and membrane structure,the orthogonal beam structure is widely adopted in the station canopy because of its simple structural form and reasonable force path.In this paper,application of orthogonal beam structure with different cable layout in the station canopy is discussed.The effect of different cable layout on the static and dynamic performance of the structure is investigated and the eigenvalue buckling and nonlinear buckling is analyzed.By using the method of elastic time-history,the anti-seismic analysis is also produced.The numerical results indicate that the reasonable cable layout will improve the carrying capacity and the seismic behavior of the orthogonal beam structure significantly.
