Abstract: Rapid developments in Erbil city along with repeated seismic activity have caused concern about the safety of reference building structures. The reference buildings might be at risk since constructed with a misunderstanding about the seismicity and without seismic code regulations. Consequently, seismic vulnerability assessment of reference building structures has been conducted which is representing contemporary buildings including commercial, hotel, and residential building, by employing detailed archetypes in finite-based modelling. Inelastic pushover and over 800 incremental dynamic analyses are performed to evaluate seismic vulnerability for the selected reference structures so that the actual response analysed with studying the influences regarding the presence of infilling masonry panels. It was concluded that the selected reference buildings are significantly vulnerable under expected seismic. It was demonstrated that there is an urgent need for seismic retrofit and strengthening for the reference building structures to reduce their seismic losses.
