Then the foundation structure, which consists of first floor slabs, foundation beams, and piles, supporting the rigid structural wall may uplift under certain circumstances and the resulting stress state may differ from the analytical prediction based on simple design assumptions. This is because the interaction between the superstructure and the foundations has not been thoroughly studied for its complexity. This study aims to experimentally clarify the lateral load resisting mechanisms considering the interaction between a structural wall, foundation beams, slabs and piles. In order to investigate the lateral load resisting mechanism of the structural wall – foundation assemblage, two types of specimens were tested. One of the specimens had monolithic wall and the other specimen had precast wall which had vertical and horizontal joints around precast wall panels. Cracks across the wall panels and along the member interfaces were a major source of deformation of the structural wall and two specimens showed different deformation modes. Nevertheless, hysteresis loops of two specimens were similar with respect to stiffness, capacity and energy dissipation. Based on the experimental results, the load resisting mechanism of the foundation beam was clarified and numerical models were proposed for different stages of deformation and damage of the wall – foundation assemblage.
