The purpose of this study is to provide efficient structural solution with economics and constructability as well as approch corresponded at the new remodeling criteria. According to the new remodeling criteria, it is generally not allow the change of the member stiffness, in addition, the load sharing between the piles and member reinforcing method are strictly limited in order to improve the safety of the structure. In this report, 8 alternative structural systems have been devised for the vertical extention of 3 floors. Through the analysis and design of each structural system, establishment of analysis method, the amount of the structural members and minimize the number of reinforcing piles were reviewed. Finally, it is expected that remodeling design will be achieved with safety, cost savings and good constructability.
