摘要
建立了索桁架屋盖体系在静荷载作用下的非线性控制方程,研究了索桁架屋盖体系的静力特性。首次求得了索桁架在静荷载作用下,其上下索网的层间接触力近似解;讨论分析了温度、索网垂度等因素对索桁架静力特性的影响。
Nonlinear control equation for the cable truss roof framing system under static load is set up to study statical feature of the cable truss roof framing system. Approximate solution to the contact force between the upper and lower layer cable wire is derived. The influence of factors such as temperature and sag of cable wire on the statical feature of the cable truss is analytically discussed.
