Abstract

Recent seismic alerts and warnings from researchers and agencies in Nigeria as regards earthquakes in the south-western part of Nigeria has led to earthquake forecast by few researchers. A team of researchers among other researchers forecasted an earthquake of magnitude 7.2 for the south-western region of Nigeria in the year 2028 while another team of researchers also forecasted an earthquake of ≥ 5.0 magnitude for the year 2028 in the same south-western region. In a bid to prepare towards these forecasted events, it necessary to design subsequent upcoming buildings around the lines of fault in the south west to resist the forecasted earthquake magnitudes. Hence this research carried out simulated response spectrum analysis on a typical modeled 3-story reinforced concrete building. The analysis was carried out using Etabs 2016 based on the specification of EURO Code 2004. The building demonstrated the highest drift of 0.010695 in the x-direction at story 2, highest deflection of 90mm in the x-direction at story 4, highest overturning moment of 36859.9947 KNm at the base and the highest stiffness of 190378.969 KN/m at story 1. To this end, the results of this response analysis should guide the designs and construction of buildings around the lines of fault in the south-western part of Nigeria in order to ensure safety of lives and properties in response to quakes in this region.
