摘　　要：预应力拱支单层网壳结构体系是在综合了单层网壳和预应力拱结构等的优点的基础上,构思出的一种新型大跨空间结构形式。本文比较了该结构体系在三种工况下的受力变形性能,结果表明该杂交结构能充分发挥两种结构形式的受力特点,整体受力性得到明显改善,显示出该新型杂交结构体系具有一定的应用前景。Based on the structural features of single-layer reticulated shells and pre- stressed arch structures, pre - stressed arch - supported single - layer reticulated shell structures have been developed as a new large space structural system. In this paper the mechanical behaviors of this structural system have been compared in three working situation. Analysis indicates that this hybrid structure can efficiently fulfill the mechanical strong points of the both and the whole mechanical behaviors have been better, thus,proving that this type of hybrid structures can be widely used.
