Seismic Assessment of Asymmetrical Existing RC Building in South of Iraq by Nonlinear Time History Analysis

Abstract

                The research aim is to assess the seismic performance of an asymmetrical RC building using NTHA. The building was built in the southern Iraqi city of Basra. Southern Iraq is categorized as a low seismic region in ISC1997, however, the current ISC2017 has been updated and contains specific seismic requirements to be applied for the construction of new buildings, prompting the need to assess the state of existing buildings concerning these new requirements. The case study is irregular in plan floors and vertically, causing it more vulnerable to severe deformations and damage than buildings with regular plan floors. The analysis is based on the ISC2017 in the design of the RSC and the modern US standard code ASCE7-16 in the selection of GMs.
