| 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．

| Abstract: | The form-finding analysis for the beam-column-supported tension membrane structures is carried out by the force density method. The interaction between the structure and the beam-column supports in the form-finding process is taken into account. Equations for the form-finding of the whole system are deduced respectively based on the theories of beam's small deformation and beam's finite deformation. 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. |
