Beam-column joint with steel fiber reinforced cementitious composite in steel structures

Abstract

This paper reports the results of an experimental examination of the structural performance of steel structures employing a beam-column joint system with steel fiber reinforced cementitious composites. The beam-column joint was achieved by filling steel fiber reinforced cementitious composites into the gap between a U-section bracket and a middle beam. Tests consisting in the application of a cyclic shear load to simple beam specimens were performed, focusing on the effect of bracket length, the effect of fiber reinforcement and the influence of loading hysteresis. The experimental results show that the specimens with steel fiber reinforced cementitious composites offer sufficient strength and ductility without prominent damage compared with the specimens employing high strength mortar and conventional concrete.
