By theoretical analysis, numerical simulation and experimental research, it is shown that compared with general suspend-dome structure and beam string structure, the force transfer efficiency, loading capacity and stability of the suspended structural system performs better. Internal forces distribution and deflection of the top grid beam are reasonable, and overall structure stiffness is improved significantly. It is also proved that local cable broken or oblique stick broken in the new-type suspended shell has little impact on the safety of the whole structure.Keywords: Shenzhen North Railway Station; canopy; suspended structural system; quadrilateral hoop cable; cylindrical lattice shell*国家自然科学基金项目（90715012，51308117）。通讯作者：孙璨，讲师，博士，Email: sunc@dgut.edu.cn。参考文献［1］张志宏,傅学怡,董石麟，等.济南奥体中心体育馆弦支穹顶结构设计［J］.空间结构, 2008, 14(4): 8-13.［2］陈志华.弦支结构体系研究进展［J］.建筑结构，2011，41（12）：24-31.［3］KITIPORNCHAI, KANG W J, LAM H F, et al.
