In the current design procedure, the structural walls are normally assumed to stand on the solid foundation. This assumption makes it possible to evaluate the seismic behavior of each member independently. However, in case that the foundation beams don’t have enough strength and stiffness to resist against seismic lateral forces, unexpected lateral load resisting mechanism can be formed. The resulting stress state may be completely different from that based on the assumption of the solid foundation. This study aims to analytically clarify the lateral load resisting mechanism of the structural wall system considering the interaction between the structural wall, the foundation beam and the piles. In order to make clear the interaction, one 25% scale specimen was modeled in two different ways. Difference of the models was with or without the pile foundation of the specimen. A pushover analysis with these models was performed. The analytical models made clear the differences of the lateral load resisting mechanism. Experimental results, such as hysteretic curve of the structural wall, deformation and damage, could be simulated well by the model with the pile foundation. It was confirmed that the upper longitudinal bars in the foundation beam played an important role in the formation of the rotational mechanism of the wall pile assemblage that were observed in experiment and analysis.
