A need for seismic design of buildings have been increased dramatically due to the fact that seismic damages have been reported all over the world. In Korea, the seismic design code for buildings was developed in 1988. However, the buildings designed and built before 1988 are expected for serious seismic damages. With this reason, an appropriate seismic retrofitting method is required for such buildings, which needs to be economical and practical. In this study, seismic retrofitting methods by using H-section steel to the slab are developed and introduced applying to the wall-type apartment buildings. As a result, performance of slab test models was improved to satisfy the required retrofitting capacity. Stiffness and energy dissipation capacity of the model were also enhanced.
