| Summary |
In frame-supported membrane structures type, one of techniques to introduce the pre-stress on the membranes is extending the boundary. In this case, the friction contact between the membrane and the frame-supported, such as steel arch, was observed. Therefore, the analytical method of membrane structures considering the friction contact is essential.
This paper describes a nonlinear finite element procedure, which includes the non-linear geometry of membrane elements and friction contact condition. In this analysis, the friction contact between membrane elements and frame-supported elements was replaced by Gap elements. The proposed method will be applied to investigate the sliding between ETFE film and steel arch of the parallel steel arch model under forced displacement condition. The accuracy and applicability of proposed procedure was confirmed by an experiment. |
