dc.description.abstract Presently, our country, Ethiopia is growing in the way of multi disciplines, such for example as: constructing for commercial, residential, and mixed used buildings. Headed for, it requires high rise buildings, which pass up scarcity of the land. Due to this aspect there is a need to study the structural system, which resists the lateral loads due to seismic effect. In this paper the seismic behavior of reinforced concrete shear walled frame and braced frame has been studied. A symmetric plan shear walled frame and braced frame has been selected, and compared the seismic response of the structural systems with the help of storey displacement and fundamental period of the building. This study has been conducted by considering different models with the aspect of changing different parameters such as: Varying thickness of shear wall, types of bracing, and compared effectiveness of shear walled frame and braced frame. Because of the structural characteristics of the building, Modal Response Spectrum analysis has been used. All analyses were carried out using finite element software‟s, ETABs version 15. When only one bay is shear walled and braced at the corner of the building in both X and y direction, the result showed that, from braced frames inverted V-braced frame showed the maximum reduction in storey displacement and fundamental time period of the frame than X-braced frame and V-braced frame. And from shear walled frames, 300mm thickness shear walled frame showed the maximum reduction in storey displacement and fundamental time period than 200mm and 400mm thickness shear walled frame. This indicates that, Increase shear wall thickness is not always beneficial for earthquake resistance design. When two bays in a row are shear walled and braced at the corner of the building in both X and y direction, the result showed that, from braced frames X-braced frame showed the maximum reduction in storey displacement and fundamental time period of the frame than inverted V-braced frame and V-braced frame. And from shear walled frames, larger thickness shear walled frame which is 400mm thickness shear walled frame showed the maximum reduction in storey displacement and fundamental time period. en_US
