摘要: 立体拱架结构体系是在综合了索及拱结构等优点的基础上，构思出的一种新型大跨度空间结构形式.作为一种轻巧、高效的大跨度结构，立体拱架结构已经有广泛的应用.为了进一步研究该结构形式的受力性能，制作了比例为1∶20的缩尺模型，并进行试验研究.结果表明：在荷载作用下，拱脚受力最大，其余构件受力较小且处于弹性阶段；索对提高结构承载力及抵抗结构变形起到非常重要的作用.

Abstract: The three-dimensional arch structure is a new style of large-span structure, which synthesizes the advantages of the arch and dragline. As a light and highly active structure, the three-dimensional arch structure has been used widely. In order to make further research on the mechanical behavior of the structure, a 1:20 scale model test was carried. The test data show that the stress of the springing is the greatest and those of the other structure parts are less. The dragline is important to improve the bearing capacity and the ability of resisting deformation.
