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*國家自然科學(xué)基金項(xiàng)目（90715012，51308117）。通訊作者：孫璨，講師，博士，Email: sunc@dgut.edu.cn。參考文獻(xiàn)［1］張志宏,傅學(xué)怡,董石麟，等.濟(jì)南奧體中心體育館弦支穹頂結(jié)構(gòu)設(shè)計(jì)［J］.空間結(jié)構(gòu), 2008, 14(4): 8-13.［2］陳志華.弦支結(jié)構(gòu)體系研究進(jìn)展［J］.建筑結(jié)構(gòu)，2011，41（12）：24-31.［3］KITIPORNCHAI, KANG W J, LAM H F, et al.
