Meshless method is a new numerical analysis scheme and researches for many analysis models have been conducted in recent years. We have applied the element free Galerkin method (EFGM), the meshless method presented by T. Belytschko et al. in 1994, to analyze membrane structure with cable reinforcement. To model the sliding cable on membrane, the arbitrary Lagrangian-Eulerian (ALE) method is adopted. By using ALE formulation, deformation of membrane and sliding between cable and membrane can be represented as different displacement components. In this paper, an ALE-EFGM formulation using the convected coordinate system for geometrically non-linear analysis is presented. Finally, the proposed method is applied to a simple analysis of membrane structure with sliding cable and its validity is demonstrated.
