Improving Seismic Performance of Reinforced Concrete Buildings with Using Steel Fibers

In this study, in order to improve the seismic performance of reinforced concrete frames using the specific amount of steel fiber in concrete is aimed. In this scope, three 1/3 geometric scaled reinforced concrete have produced according to the TEC-2007 rules. One of the three frames is called as a reference (S1) which has been produced with normal concrete. The others have produced with different fiber amount in the concrete. The selected amount is 30kg/m^3 and 60 kg/m3 for S2 and S3, respectively. The three different specimens have been tested under earthquake resembling cycling lateral loading, the stiffness and lateral loading capacities have been obtained, experimentally. At the end of the study, it has been seen that the seismic performance of S2 is better than S1 and S3with respect to initial stiffness and lateral loading capacity.
