The Load-Bearing of Concrete Beams as the Steel Reinforcements Connected by the Coupler at a Cross-Section of a Beam

摘要

In this paper, the authors investigated the effect of the position and the splicing ratio of reinforcement bars by coupler on the behavior of reinforced concrete beams. The experimental samples gave the assessments with the reinforcement concrete beams with steel bars connected by coupler at the same cross-section. For supporting the results from experiments, a nonlinear finite element analysis was performed with the help of ABAQUS software. Comparison results of beams with/without coupler showed that the load capacity and behavior of reinforced concrete beams with the couplers have relatively small changes compared to concrete beams without splice on steel bars.
