Effect of infill walls on limit states in reinforced-concrete frames

Abstract

In this study, the infill wall effect was investigated for a reinforced-concrete frame consisting of three different openings. Five different structural models have been created such as completely filled, gap in the corner, double gap and completely bare on the ground floor. The results of static pushover analysis and eigenvalue analysis, which were made by considering only the absence of infill wall as a variable, were compared. The target displacement for performance levels, period, base shear force, elastic and effective section stiffness’s were obtained separately for each structural model. The study revealed once again that the amount of infill wall contributes significantly to the seismic capacity of the building.
