  7. Abstract:
  8. Using mixed building system of structural steel and reinforced concrete improves the resistance of the structure in comparison with using either material alone. Coupled shear walls is one of these new systems. Coupled shear walls by definition is a series of walls coupled by beams as a central core structure with opening to accommodate doors, elevator wells, windows and corridors. Coupled shear walls can provide an efficient structural system to resist horizontal force due to axial and seismic loads. One type of coupled beams is Steel Coupling Beams (SCB) which consists of steel beams and reinforced concrete shear walls which represents a cost and time-effective type of construction. Some new approaches, based on the experimental evaluations have been developed on coupled shear walls. However in all of them it is not possible to replace the coupled beams after damages due to earthquakes. Recently a new experimental research has been carried out at Sharif University of Technology that makes it possible to replace or repair the link beam after experiencing damages. In this study steel coupled beams will be analyzed using FEM (Finite Element Method) analysis. The software which is distinct in this study is ABAQUS 6.6-1 .The results based on FEM will be compared with experimental data obtained at SUT. Besides that an attempt is made to suggest a revised model in order to improve some strength characteristics of the experimentally tested model. At last the main object of this study is to propose a proper model which has either replaceable or repairing ability after damages and enhance the strength of steel coupling beam-wall connection in hybrid wall system
