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．
The proposed fan trapezoidal suspension cable roof structure is another new type of suspension cable structure characterized by a unique shape and easy drainage. In this paper, nonlinear elastic theory is applied to the finite element static analysis of this structure, and the tension of each element is adjusted by the uniform adjustment method. The coordination adjustment method is also adopted to consider the mutual influence of the suspension cable and the ring beam. The ring beam of the anchorage suspension cable adopts a double-layer space frame structure. The advantages of this structure are small deformation and good bending resistance.
