Flexural behavior of concrete beam-column connections in hybrid structures under static load.

This paper aims to study the behavior and load carrying capacities of a hybrid connected beam-column joint when loaded under static conditions. This research aimed to investigate and observe how slurry infiltrated fiber concrete (SIFCON) affected the results. One ratio is dependent now, 7% percent for each type of steel fiber, such as hook end steel fiber, micro steel fiber, and hook-micro fiber, to observe its effect in SIFCON. Experimental work includes evaluating a beam-column joint, one specimen of which employs regular concrete only, and the others cast with SIFCON in the crucial portion in addition to regular concrete. Ultimate load capacity compared with a control specimen showed that specimens with SIFCON were more efficient than those without SIFCON. As a result of employing a SIFCON, the increase ratio for enhancing ultimate loads raised to (37.5%, 18.75% and 26.25%) for samples using hook fiber, hook+ micro steel fiber, and micro steel fiber, whereas hook end steel fiber showed better flexural strength than micro steel fiber.
