摘　　要：为了提高单层网壳结构的稳定性,将格构式压杆引入单层网壳,提出了空腹网壳的概念。空腹拱是空腹网壳的组成个体,目前对其性能的研究非常少。本文对空腹拱的静力性能做了一些研究,利用有限元软件对若干组空腹拱进行计算,得出在不同参量变化中空腹拱结构的内力改变情况,并了解空腹拱的受力性能。In order to enhance the stability of single layer dome, vierendeel dome is presented by employing lattice bar. The paper puts forward a spatial vierendeel dome concept. Vierendeel arch is the key part of vierendeel dome, on which research is few. This article studies which researches the static performance of vierendeel arch, calculates several groups of vierendeel arches in use of finite element software. Then we find out the mechanical performance of vierendeel arch including internal forces and displacements, when different parameters change.
