Various Existing Methods of Coupling Beams and a New Alternative Hybrid Method

The performance of various existing methods of coupling beams is summarized, including the disadvantages and advantages. According to previous researches reporting the utilization of diagonally reinforced concrete coupling beams for deep beam is essential and is the best solution to provide adequate ductility in coupling beams. However, diagonally reinforced concrete coupling beams have difficulties in practice due to congestion of reinforcement. With the purpose of simplifying construction, an alternative approach for the design of composite coupling beams will be suggested for further studies in experimental research through the use of hybrid component, which is a combination between ordinary reinforced concrete beams that will resist the flexure and steel trusses that will resist the development of high shear in the coupling beam. The proposed method will be compared to the performance of diagonal reinforced concrete coupling beams according to guideline SNI-2847:2013.
