Abstract: Resisting in-plane loadings is an important issue in the field of glass structures. Glass structures are connected to each other in two ways, and then they connect to the substructure: 1) point supports; 2) linear support; where the first one is more common. Several point supports have been examined by researchers and their stress distribution and failure mechanisms are analysed, but point supports have not been analysed using hyperelastic materials. In this paper, a point support is studied numerically under axial load, then the specimen is modelled using hyperelastic material and the results are analysed and compared to each other. Considering stress distribution and load-displacement diagrams of glass frame model by hyperelastic contact, and comparing them with glass frames containing usual contacts leads to following result: according to hyperelastic materials' properties, which are the same as nonlinear elastic ones, the stress in support contact with glass is 50% lower, and also having less displacement in comparison with glass frames using normal contacts. Based on the results, the glass frames with hyperelastic materials resistance much more load than the ones with normal contacts.
