摘要
提出了扇形弓弦预应力组合结构的概念，介绍了该结构的特点和受力机理；应用算例的方式依靠有限元软件ANSYS对结构进行了静力计算，分析了施加预应力的方式和施加预应力的大小对结构受力性能和变形性能的影响。提出的基本概念可供相关结构的设计和工程应用参考，也为土木工程结构体系增添了一种新的结构形式。
The conception characteristics and load-bearing principle of the prestressed sector-bowstring structure were represented in this paper, ANSYS was adopted to perform mechanics calculation on a numerical model. The effect of the value and acting way of prestressing force on load-bearing and deformation of structure was analyzed, It can be used as reference in structural design and application. Raising the conception of the prestressed sector-bowstring structure added a new form of structural system in civil engineering.
