Study on Earthquake Response of Composite, Steel and RCC Structures for Addis Ababa Condominium Housing
Reinforced concrete framed structures are widely used in Ethiopia. But there are alternative options for designers to decide structural system for a particular building. Comparative study of RC, steel and composite framed condominium buildings is done in this paper to evaluate better structural system regarding overall economy, structural performance, construction time etc. To conduct the intended research work, architectural layout plan of G+15 condominium building with two basements from Addis Ababa housing development office is selected which is located in Ayat. Structural modeling and analysis have been performed by ETABS 2016. Loads are assigned following the EBCS EN 1992-2013. The research outcome shows that the fundamental period (First mode time period) of RC structure is about 36% lower than steel structure and 16% higher than Composite structure. The maximum roof displacement for the X-direction for RC structure is 41% lower than steel structure and 26% higher than that of Composite structure. The maximum roof displacement for the Y-direction for RC structure is 55% lower than steel structure and 31% higher than that of Composite structure. And cost of composite structure is 5% lower than RC structure. RC Structure for earthquake response in the X-direction base shear shows 1.1% decrease when compared to the composite structure. For earthquake response in the y-direction the base shear in RC structure shows 4.8% increase when compared composite structure. The maximum axial load for RC structure is 11% higher than steel structure and 7% higher than that of Composite structure.
