Abstract: 
In this paper, the seismic behavior of typical Iranian buildings with ordinary moment-resisting reinforced concrete frames is evaluated. The evaluation results indicated that these structures, which were designed based on 2800 standard (1366 edition) and before, due to ductility and stiffness deficiency, don"t satisfy the new 2800 standard (second edition) requirements. Concrete buildings with ordinary moment resistant frames with four and ten stories are investigated. The effectiveness of two retrofit schemes, ordinary concentric steel braces (CBF) and Added Damping And Stiffness steel plate energy dissipaters (ADAS), examined. The results of investigation indicated that, although CBF retrofit scheme (more traditional one) is efficient in stiffness increase and lateral displacement reduction, but increases the internal forces of some structural elements (specially braced columns and their foundation). Due to limited capacity of these elements, this scheme doesn" t satisfy the retrofit objectives. The ADAS dissipater, in contradiction of CBF system, doesn" t produce significant increases in structural seismic forces. Retrofitted structures with ADAS are able to sustain earthquakes, which are stronger than design earthquake. Nonlinear static pushover analysis conducted using ATC-40 capacity spectrum method.
