Seismic performance evaluation of reinforced concrete structures

In this study, it is aimed that evaluation seismic performance of reinforced concrete structures. It is adopted that for nonlinear behavior of reinforced concrete element section with plastic hinge assumption. Two-computer program are prepared for nonlinear analysis of plane frame and for scaling real acceleration records according to elastic design acceleration spectrum in Turkish Earthquake Code. For numerical application, two irregularity states are investigated. These irregularity states are; no edge frame beam and soft story irregularity. Nonlinear pushover analysis of building of no edge frame beam is performed and is compared with buildings of edge frame beam which with rigid and flexible diaphragms. For investigation of soft story irregularity, nonlinear pushover analysis of three frames that different height of first floor are performed and are compared.
