Seismic responses of twenty-storey reinforced concrete frame structure in akhalia, sylhet Bangladesh

In the high earthquake era, the efficient performance evaluation of reinforced concrete building structures has become a key issue. In this paper, based on the nonlinear dynamic evaluation method of structural seismic performance atwenty-storey reinforced concrete building structure seismic assessment was carry out. the building structure was considered to be built in Akhalia, Sylhet Bangladesh. Four recorded ground motions were matched with Bangladesh National Building Code (BNBC) 2017response spectrums and scaled to PGA of 0.25g,0.30g and 0.35g. Therefore, nonlinear dynamic time history analyses were carry out using the matched and scaled ground motions and the seismic performance of the structure was analyzed. It can be seen that the seismic performance of the selected project of twenty-storey reinforced concrete frame structure is excellent. Thus, the platform based on the concept of seismic evaluation structures demonstrates a general agreement that an efficient and accurate assessment of reinforced concrete frame structures can be achieved.
