摘要
广东省清远市体育馆为正大边形平面，采用六块单轴对称的双层扭网壳组合而成。每块扭网壳在支座处采用异钢种预应力钢结构，使屋盖用钢量下降了３５％。本文讨论它的设计、构造与力学特点，并提出在多索张拉时，施工张力计算的简单方法──刚度聚合法。
Abstract The roof of the gymnasium in Qingyuan City,Guandong is of combination type doublelayer twisted net shell,with hexagonal plane,single axis in symmetry.Each of the twisted netshells is constructed in the way that the steel needed would decrease by 35%.In this paper,thedesign,structure and the mechanic characteristics are discussed.And a simple calculation methodfor construction tension Rigidity Concentration Method is provided.
