Recently, a structural analysis using new type discrete model was developed by T. Kawai, and it has been applied to limit state analysis of structure and solid. In this paper, non-linear structural analyses by two-dimensional hybrid stress model are presented, where the elements idealized by T. Kawai are applied. Since the elements have a node at mid-point of length of the each boundary side, the analysis is useful for treating non-linear problems including crack and slip. Herein, the hybrid stress model is applied for the bearing capacity of a concrete block, the load carrying capacity of reinforced concrete beam and contact problems of two elastic bodies.
