After performing a nonlinear time history analysis of an apartment for vertical extension remodeling, the characteristics of the model including a pile foundation and the pinned base model without including a pile foundation on the nonlinear behavior of a superstructure were analyzed. By introducing vertical and horizontal stiffness to the pile, the constraint effect of the ground was defined. In the case of insufficient strength of the pile during the construction stage, micro piles were additionally placed. The nonlinear properties of the superstructure were the same as the typical performance-based seismic design procedure, and the nonlinear dynamic analysis of the 7-pair earthquake motions were performed for the pile foundation model and the pinned base model. As a result of this analysis, it was found that the story drift and material strains of the pile foundation model increased compared to the pinned base model. In addition, the base shear force was reduced in the pile foundation model compared to the pinned base model, and the pile reaction force in the pile foundation model was also reduced. This is thought to be the effect of reducing the response spectrum acceleration value due to the increase in the natural period of the pile foundation model.
