A number of piloti buildings were used as a multi-family housing because of their relative low cost maintenance and availability of enough parking spaces. However, this type of structures were somewhat severely damaged due to recent earthquakes in Korea. In general, piloti structure shows a relatively weak story in the first story compare to the rahmen structure due to the soft story irregularity. As a result, non-elastic deformation of structural members of the weak story can occur intensively, and then resulting in a sudden change in the seismic load flow which can lead to the member's brittle failure. Moreover, the damage of the piloti structure can be differed from many factors such as the location of the core surrounded by the wall. In this study, a nonlinear time history analysis was used to analyze how the piloti structure responds according to the core location and how the damage changes when the piloti structure deterioration. Test results show that the eccentricity of the Piloti structure increased, the natural period of structure was increased. In addition, as the eccentricity increased, the damage of the vertical members were increased in the weak story.
