Structural Analysis of Hybrid Tensile Structures Consisting Of Cable, Membrane And Rigid Members

摘要

Hybrid Structures consisting of cable, membrane and rigid members are examined in the present paper. Kinematic equations and equilibrium equations for cable element, rigid structure and membrane element are formulated by means of generalized inverse method. The freedom of rigid structure is considered by the displacements of its nodes so that the relationship of the displacements of nodes is obtained from its kinematic equation. By regarding the rigid structures as constraint conditions of displacements using their kinematic equations, structural analysis scheme is proposed for static and dynamic analysis as well as shape finding analysis.
