Abstract |
Reinforced concrete coupled shear walls in tall buildings are known as efficient structural systems to provide lateral resistance to wind and earthquake. The coupling beams connecting two shear walls are normally subjected to very high shear stresses and must before the wall piers, behave in a ductile manner, and exhibit significant energy dissipation characteristic. This paper reports experimental study to investigate the behavior and shear force of the steel plate reinforced concrete coupling beans with stud shear connector, deformed reinforcement, and channel under cyclic loading. In the test program, 3 steel plate coupling beam specimens are constructed and tested. The main variables in the test program were the attached reinforcement details of steel plate. Steel plate reinforced coupling beams with concrete were tested to evaluate their failure mode, shear behavior, stiffness characteristic, energy dissipation, and plate strain. The results of these experiments demonstrate that it is possible to significantly improve the strength, displacement capacity, energy absorption of shear deficient reinforced concrete coupling beams. |
