摘要
某高速铁路站房屋面采用大跨度钢网架结构体系,网架平面投影形状呈“凸”字型,最大跨度约51.6 m,高低屋面高差约4 m。针对该项目大跨度钢网架结构进行概念设计、弹性分析、抗震性能优化设计和抗连续倒塌分析,确保了该屋面结构具备足够的安全度,可为类似钢网架结构的设计提供参考。
The roof of a high speed railway station adopts a large-span steel grid structure.The projection of this gird structure is T shaped,with a maximum span of about 51.6 meters and a height difference of 4 meters between the high roof and the low roof.This article carried on the conceptual design,elastic analysis,seismic performance based design and resist progressive collapse analysis of the large-span steel grid structure of this project,ensuring that the roof structure has adequate safety redundancy and provides reference for the design of similar steel grid structures.
