摘要
对预应力张拉索膜结构由于温度变化对结构初始平衡形状和静力效应的影响进行研究。考虑温度作用对索膜结构形态和受力特性的影响,在推导索膜结构在温度作用下找形分析和静力分析的非线性有限元方程的基础上,进一步研究温度对索膜结构初始平衡形状和静力特性的作用效应。通过算例分析,探讨不同温度变化作用下的索膜结构初始几何形态、内力和位移的作用效应,并提出工程建议。
The temperature effect on initial equilibrium shape and characteristics of static responses of pretcnsioned cable-membrane structures is analyzed in this paper. Considering the temperature effect, nonlinear finite element equilibrium equations for form finding and static behavior analysis of cable-membrane structures are derived, then the temperature effect on initial equilibrium shape and characteristics of static responses are studied. Example analysis demonstrates the change of initial shape, internal forces and deflections of cablemembrane structures under different temperatures. Some engineering suggestions are presented from the analysis results.
