Comparative Seismic Performance of MRF, Dual System and Shear Wall in RC Buildings

Behavior of multi-storey buildings subjected to different loadings specifically earthquake loads is always a subject of interest for structural engineers. With the increased frequency of earthquakes and more awareness about the design requirements and codal provisions it is extremely important to study the behavior of the structure with different structural frame configurations and their suitability. Moment resisting frames (MRF), dual system and shear wall dominated systems are three basic and widely used load resisting systems for medium high rise buildings. In this study the seismic performance of all the three systems is compared to find out strength and weakness of each system. A RC building is modelled using STAAD PRO software with different possible configurations for the three systems. The parameters considered for the comparison are inter- storey drift, storey shear, total displacement and time period. It is concluded that shear wall dominated system shows better performance than the other two systems under seismic loading.
