| 摘 要： | 拱支网壳结构体系是在综合了网壳(网架)及拱结构等优点的基础上,构思出的一种新型大跨度空间杂交结构形式.为进一步研究该结构形式的受力性能,本文制作了以K6-4型(Kiewitt型)单层网壳结构为基础所构成的两种具有代表性的拱支网壳结构模型,进行试验研究,同时还采用一个同尺寸的纯单层网壳模型作对比试验,并将试验结果与理论分析结果进行比较.结果表明,由于拱结构的参与,该杂交结构的受力性能得到明显的改善.

| Abstract: | The arch-supported reticulated shell is a new type of hybrid spatial structural system. in order to know more about the behavior of hybrid structures, an experimental research on two typical hybrid shells and a normal single-layer reticulated shell is performed in the paper. The results indicate that the bearing capacity of the hybrid structure is greater than the normal one. The ductility of the hybrid structure is obviously improved. At the same time, the analytical theory and developed program for hybrid structures are verified to be correct and effective |
