中文摘要：
叉筒网壳是一种由若干组圆柱面网壳相贯得到的空间结构,具有独特的建筑造型与受力性能.由于其传力路径简捷,主要集中于脊线或谷线,对边界约束要求较高,一定程度限制了其应用和发展.本文提出了一种新型索承叉筒网壳结构,并给出了三种不同的分类方法,较全面地概括了索承叉筒网壳结构的形体和种类,并提出了将索承叉筒网壳作为结构单元进行组合,构建大面积结构的设想.最后,以十二边形谷线式弦支叉筒网壳为例与叉筒网壳对比,并进行了参数分析,结果表明索承叉筒网壳结构静力性能得到较大的改善.
英文摘要：
The latticed intersected cylindrical shell （LICS）, which has individual architectural shapes and mechanical properties, is derived from the intersection of a certain number of cylindrical latticed shells. The path of conducting force is simple, finally comes together at the ridge or valley. So more requirements are proposed on the boundary constraint, which restricts the application and development of the I.ICS. This paper introduces a new type of spatial structure named cable-supported LICS and provides three methods of classification. The types of cable-supported LICS are summarized comprehensively, and an assumption is put forward that a large area of structure could be combined by cable-supported I.ICS. A dodecagon valley-style suspen-LICS and its parameters are studied. By comparison with I.ICS without prestress, it is proved that the static behavior of cable-supported LICS is improved.
