Seismic Performance of SFRC Beam-Column Joint with Corbel under Reversible Lateral Cyclic Loading

Abstract—Seismic performance of full-scale precast beam-column end joint with corbel mixed up together with Steel Fibre Reinforced Concrete (SFRC) is examined. The sub assemblage of beam-column joint was tested under reversible lateral cyclic loading up to ±1.5% drift. The visual observation and experimental results showed that the cracks start to occur at +0.75% drifts (pushing direction) at the cast-in-situ area in beam-column joint. Experimental result ofthe hysteresis loops (load versus displacement) showed a good agreement with the theoretical result obtained from moment-rotation analysis method. The elastic stiffness, secant stiffness, ductility and equivalent viscous damping forbeam-column joint are also determined in this paper.
