Title Meshless Analyses for Design of Cable-reinforced Membrane Structure
Author Tetsuya Kawashima,Hirohisa Noguchi,Kazuo Yokohori
Summary In the analysis of cable-reinforced membrane structureEŒthere are several complicated problemsEŒsuch as the fold of membrane by cableEŒsliding of cable on membrane surface and so on. As finite element method (FEM) can hardly to analyze these problemsEŒauthors have applied the element free Galerkin method (EFGM)EŒthe meshless method presented by T. Belytschko et. .al. in 1994EŒto analyze membrane structure with cable reinforcement. To model the sliding cable on membraneEŒthe arbitrary Lagrangian-Eulerian (ALE) method is adopted. By using ALE formulationEŒdeformation of membrane and sliding between cable and membrane can be represented as different displacement components. AdditionallyEŒconvected coordinate system is utilized for geometrically non-linear analysis. In this paperEŒthe proposed meshless method is applied to several numerical analyses of membrane structures with sliding cable.
