摘要: 用力密度法对梁-柱支承的张拉膜结构进行找形分析.在找形过程中考虑了膜体与梁-柱构件之间的相互作用.文中推导了结构体系的整体找形公式,其中梁-柱结构分别采用了小变形理论和有限变形理论建立模型,并编制了相应的找形分析程序.通过算例对这种带梁-柱支承的膜结构整体找形问题进行了分析和讨论,结果证明了文中方法的可行性.

关键词: 梁-柱支承, 张拉膜结构, 整体找形

Abstract:

The form-finding analysis for the beam-column-supported tension membrane structures is carried out by the force densitv method.Th e interaction between the structure and the beam-column supports in the form -finding pmcess is taken into account.Equations f0r the form.finding of the whole system are deduced respectively based on the theories of beam ’s small deform ation and beam ’S finite deform ation. Moreover,the corresponding software for the form-finding analysis is developed.Discussions about the integral form -finding of the membrane structures with beam-column supports are finally given by examples.The results prove the proposed method feasible.

Key words: beam-column support, tension membrane structure, integral form-finding
