Abstract:In multistory framed structures, three kinds of connections exist, namely, cross-type, tee-type, and knee-type. Experimental investigations were made to study the behavior of 50 such beam-column connections of conventional and steel fiber concrete (SFC) when tested under static, as well as slow-cycle fatigue, loading. In all, 10 cross-type specimens of full-scale two-span beam with column stub were tested. Four cross-type connections were cast with conventional concrete, two with steel fibrous concrete in the entire length and four with SFC in the joint region only. The test results showed that SFC improved the ductility at the joint region, increased load-carrying capacity, decreased crack width, eliminated shear reinforcement, and overcame the problem of spalling of concrete in the joint region. The testing work also included 20 tee-type and 20 knee-type connections with 12 of each tested under static load and eight under slow-cycle fatigue load. The percentage was kept as 0.0, 0.6, 0.8, and 1.0 of concrete volume. Instrumentation was done to measure deflections, rotations, strains, and crack widths.
