Abstract :The first defect was related with concrete for RC buildings that damaged after an earthquake. In this study, effects of concrete class on structural performance of reinforced concrete building have been investigated. Çeltiksuyu School building that has collapsed after 2003 Bingöl earthquake was selected to obtain realistic results. Calculations have been made for each concrete class which was selected as C8, C16, C20, C25 and C30. Pushover analyses were used for both direction of selected building. As a result, structural behaviour of RC buildings with different concrete classes is compared and evaluated according to analysis results in detail. The displacement and internal forces obtained from results of analysis is investigated comparatively. The results show that base shear of building was increased according to increasing concrete strength. The increasing in base shear has been increased the amount of peak displacement in the structure. As a result, it can say that concrete strength was not too defective. The main issue is manufacturing of concrete has not been made under proper conditions. The reason for this is lack of control, workmanship and material defects.Keywords : Structural performance, conrete class, strength, pushover analysis
