Abstract
In the present study, reinforced concrete dual system building have been designed by unified performance-based design (UPBD) method for various target performance objectives. In such buildings, lateral load is mainly taken by shear wall and gravity load is taken by frame. Proper engineering procedure is required for apportioning and designing shear wall and frame members. The designed building are subjected to static and dynamic non-linear analyses. The shear wall is modeled as a layered shell element, whereas the beams and columns are designed as frame elements using ETABS-2016 software. In this study, frame-shear wall building of height 12 storeys has been considered as sample building. The building has been designed with expected strength and demand level of EC-8 spectrum at 0.45 g. The target performance objective is considered as Life safety (LS) performance level with 2% drift. Various performance parameters like performance point, design drift, equivalent damping, and base shear have been found out. It has been observed that the target performance objectives have been achieved. KeywordsPerformance-based designUPBD methodRC dual systemMulti-layer shell elementPlastic hinge
