In the 2016 KUMAMOTO earthquake, the R/C soft-first story building designed after 1981 was severely damaged. To mitigate the damage, study on seismic retrofit with UFC panels has been conducted. Investigation to evaluate structural performance of the retrofitted building with soft-first story is necessary. This paper presents an analytical model for the retrofitted R/C soft-first story frame specimen with UFC panels. The modeling method for such as column retrofitted with UFC panel are discussed, especially it’s focused on structural performance of this retrofitted specimen dependents on mortar in joint between UFC panel and concrete stubs.
