Abstract: The efficiency of coupled shear walls in high rise buildings is the key factor for the performance of overall structure during seismic hazards. The coupling beams in a coupled shear wall dissipate seismic energy and act as a fuse between two shear walls and attain maximum damage in earthquake. The objective of this research is to observe the nonlinear analytical behaviour of coupling beams by using ETABs and to select appropriate section from conventional reinforced concrete coupling beams, steel link beams and composite steel – concrete coupling beams in a high seismic zone. From the nonlinear static analysis it isclearly observed that coupling beams behaves as a shear dominated beams rather than flexure. The steel link coupling beams deformed in a more ductile way as compared to the RC coupling beams and composite steel-concrete coupling beams. The concept of Braced Coupled Shear walls is also presented in this comparative study.
