现有的关于半刚性节点单层空间结构的研究大多集中在球面网壳上。本文对方形平面单层结构进行了分析，研究了节点刚度对结构受力性能的影响。对一个5 × 6 m的单层柱面网壳进行了半刚性螺栓球节点的试验研究。对网壳结构的受力性能进行了详细的研究。考虑材料非线性和几何非线性，建立了网壳结构的有限元分析模型。结果表明，使用有限元模型确定的行为与实验观察到的行为与半刚性节点的单层结构。(C)2014爱思唯尔有限公司版权所有。
Most existing studies on single-layer spatial structures with semi-rigid joints were focused on spherical domes. The present paper analyzed the squared plan-form single-layer structures, examining the influence of joint-rigidity on the mechanical performances of the structures. An experiment has been conducted on a 5 x 6 m single-layer cylindrical reticulated shell with semi-rigid bolt-ball joints. The mechanical performance of the latticed shell is investigated in detail. Finite element analysis (FEA) model of the latticed shell is established taking material and geometric nonlinearities into account. The results show that the behavior determined using the FEA models correlates well with the experimentally observed behavior for the single-layer structures with semi-rigid joints.
