摘　　要：提出的扇状梯形悬索屋盖结构，是又一新型悬索结构，特点是造型别致，易排水．本文应用非线性弹性理论，对此结构进行了有限元静力计算分析，并对各索单元张力采用均匀调整法进行调整，计算中还采用了协调调整法考虑悬索和圈梁的相互影响．锚固悬索的圈梁采用了双层空间框架结构形式，这种结构的优点是变形小，抗弯性能好等．In this paper a fan-shaped and Ladder-shapded cablesuspended roof structure has been designed It is a new cable-suspended roof .This structure has advahtage with beautiful and delightful structure being easy to drain water.According to the nonlinear elastic theory,the finite elenment statics caoculat_ion is used to cinsider the influence betneen cable-suspended and circle beam ./The beam that anchored cables adopt a double-deck space circle form.The beam hasthe advantages of small deformation and good retited bending propetry .
