Comparative Analysis of Seismic Loading on High-Rise Steel Building Structures in Bujumbura and Kigali Cities

Abstract eng:
The seismic loading analysis is very important for designing high-rise buildings in the most seismic ground motions zone. The objective of this study was to compare some seismic loading forces on two similar high-rise building structures located in Bujumbura city (Capital of Burundi) and Kigali city (Capital of Rwanda); using ETABS software .These two cities are located in the Western side of the East African rift system; known as the African most seismic ground motions zone. In the present study, all the seismic design data were the same for the two buildings except their seismic site spectral response acceleration Ss and S1.The result of the study showed that the average of the seismic base shear forces and the seismic stories lateral forces on the building located in Bujumbura city is ranged between 2.3 and 2.4 times greater than the average of these seismic loading forces on the building located in Kigali city.
