  The problem of overcrowding at the junction of the rebars is very significant, particularly for seismic details. Mechanical couplers can, thus offer an appealing solution that eliminates the disadvantages of traditional reinforcement splicing. By identifying the target area for bar failure, the potential area for failure could be modified with this in mind, it is very useful in assessing the position of the reinforced concrete (RC) plastic hinge. In this context, the present study focuses on the numerical and analytical modelling of the experimentally obtained response of Integrated bar (without coupler) and bars with mechanical coupler to tensile uniaxial tests. Simulation results showed agreement with the experimental response in terms of load–elongation curve, Von Mises yield and failure mode .After validating the model, alternative designs (diameter, height and thickness of mechanical couplers and bar) were numerically tested to study the influence of the geometry of the structural system on the failures mechanical coupler. Overall results indicated that the optimum design would be the one with an increased diameter in the thread area of both the bar and the mechanical coupler. For this improved configuration, the load-bearing capacity was Similar to the Integrated bar (without coupler) Cases. Manuscript profile

  This study presents a comprehensive evaluation of the performance of oversize threaded splices under cyclic loading conditions. The research includes monotonic tensile testing and cyclic loading experiments to investigate the seismic behavior of the splices. The experimental results demonstrate that the splices exhibit lower values of εu (strain at peak load) in cyclic loading compared to monotonic tensile testing. This suggests that the cyclic response can serve as a conservative lower bound for the mechanical performance of the splices. The findings highlight the importance of considering cyclic loading conditions when determining conservative lower bounds for the design and evaluation of threaded splices. Understanding the behavior and performance of threaded splices under cyclic loading is crucial for ensuring their reliable and safe operation in seismic regions. Manuscript profile
