［摘要］单层折面网壳是近年来新兴起的一种由三角形折面网格组成、外形如宝石群或宝石晶体的单层网壳结构。为改善单层折面网壳的受力性能、提高结构刚度、优化结构设计，可在其基本结构体系的基础上增设若干道预应力环索。以铰接B6,8型单层折面网壳为例，通过模型静载试验验证了理论分析的可靠性，对比分析了结构施加预应力前后的受力性能，并在施工张拉模拟试验的基础上给出了合理可行的张拉施工方法。［关键词］预应力单层折面网壳; 试验研究; 模型设计; 静力加载; 施工张拉中图分类号：TU394 文献标识码：A 文章编号：1002-848X(2016)04-0015-07
Experimental study on prestressed single-layer folded-plane reticulated shell structureXing Dong1,2, Dong Shilin2, Liu Changjiang1, Zhu Mingliang3（1 Institute of Civil Engineering and Architecture, Weifang College, Weifang 261061, China; 2 Space Structures Research Center, Zhejiang University, Hangzhou 310027, China; 3 College of Civil Engineering, Southeast University, Nanjing 210096, China）Abstract:The single-layer folded-plane reticulated shell which is proposed recently is a kind of single-layer reticulated structure composed of triangular lattices, just like an assemblage of diamonds. In order to optimize behavior characteristic, structural stiffness and structure design of the single-layer folded-plane reticulated shell, several ring cables could be add up to the basic structure system. For further study, static loading experiment on B6,8 single-layer folded-plane reticulated shell was carry out. The theoretical solution result is in a good agreement with experiment result, a contrastive analysis about structural behavior before and after prestressed was made, and a reasonable prestressed construction method is suggested.Keywords:prestressed single-layer folded-plane reticulated shell; experimental study; model design; static loading; prestressed construction
