Structural performances for both before and after strengthening states are evaluated, also taking into account the existence of infill walls for the as-built and strengthened states of the building. Pushover analyses are carried out to establish the capacity and demand curves for the structures, selecting the target displacements considering the Turkish Earthquake Resistant Design Code-2007. Utilizing DRAIN-2DX computer program, dynamic analyses are performed using an earthquake ensemble of 7 recorded strong ground motions as well as a simulated spectrum compatible accelerogram. It is assumed that, bilinear hysteretic model represents the nonlinear force-displacement relationship of structural members of frames, while all infill walls are modeled as compression struts. Envelopes for generalized and relative displacements and time variations of overturning moments and roof displacements with respect to base-shear are determined and these demands are compared for the two states of the structure. It is clearly exhibited that inclusion of infill walls led more realistic results, not only for estimation of occurrence of plastic hinges but also consistency of analysis and site inspection of damaged structure.
