SUBSTITUTION OF THE TRANSVERSE REINFORCEMENT WITH ENGINEERED CEMENTITIOUS COMPOSITE IN RC EXTERIOR BEAM-COLUMN JOINTS SUBJECTED TO CYCLIC LOADING

This paper presents a comparative study to investigate the seismic behavior of RC exterior beam-column joints subjected to cyclic loading. Two specimens of full-scale RC beam column joint were cast and prepared for testing. The first specimen was cast with conventional concrete (CC) and seismically designed according to ACI 352R-02 structural connection Type 2. For second specimen, the CC and the transverse reinforcement in the joint region were substituted by engineered cementitious composite (ECC) using synthetic polyethylene (PE) fibers. The specimens subjected to a reversed cyclic loading at the end of the beam under controlled deformation until failure.
