Development of Simple Mechanical Splice for Shear Reinforcement and Experimental Study on Its Application to RC Members

Abstract

In order to reduce the labor needed in the arrangement of shear reinforcement, a new method of simple mechanical splice for shear reinforcement was developed. And also in order to examine the effect of this splice on mechanichal performance of RC member, (a) tensile test for reinforcements using developed splice, (b) uniaxial compression test for RC columns, (c) flexural-shear test for RC beams, and (d) reversed cyclic loading test for RC columns, were carried out. In these tests for RC columns and beams, the comparisons between specimens with shear reinforcement using conventional anchorage and using developed splice were made. Test results indicate that shear reinforcement using developed splice as well as using conventional anchorage have the effectiveness of preventing the buckling of the longitudinal bars, confinement associated with shear reinforcement, and shearing performance.
