Abstract

Finite element analysis was conducted on a R/C residential building with soft first story which was built in 1992 and heavily damaged in the 2016 Kumamoto Earthquake. Structural damage observed on first story column and second story beam members of the soft first story could be predicted in good accuracy. By carrying out a parametric study, it was found that the detail of second floor beam and wall above the soft first story affect to the horizontal load carrying capacity and deformation capacity of whole building.
