北京南站是一座集普通铁路、高速铁路、市郊铁路、城市轨道交通、公交及出租等市政交通设施于一体的大型综合交通枢纽工程,其雨篷结构体系首次采用了A字形塔架柱和工字钢悬垂梁组成的空间结构体系。探讨了北京南站雨篷新型结构体系选型原理及特点,并对雨篷结构进行了包括静力分析、地震分析、整体稳定分析及构件有效长度计算在内的详细分析。研究表明,北京南站采用的新型结构体系不仅满足静力荷载组合下的安全要求,而且具备良好的抗震效果,是一种经济、安全、高效的空间结构形式。
Beijing South Railway Station is a large-scale integrated transport hub project that integrates municipal transport facilities such as ordinary railways, high-speed railways, suburban railways, urban rail transit, public transport and rentals. Its awning structural system adopts the A-shaped tower column Structural steel system consisting of a steel suspension beam. The selection principle and characteristics of the new structural system of the Beijing South Station awning are discussed. A detailed analysis of the awning structure including static analysis, seismic analysis, overall stability analysis and component effective length calculation is carried out. The research shows that the new structure system adopted by Beijing South Railway Station not only meets the safety requirements under the combination of static load but also has good seismic resistance, which is an economical, safe and efficient space structure.
