Abstract

In this research in-plane shear Behavior of composite steel-concrete shear walls was investigated considering the Effects of steel plates thickness, spaces between shear studs, shape and type of shear studs and existing of minimum reinforcement in wall section. Several finite element models were analyzed and Numerical results of two models were taken under verification with existent experimental results.numerical results coincide experimental result with an acceptable accuracy.numerical models analysis results show that increasing steel plate thickness, yield shear strength and ultimate shear strength become higher. Increasing shear stud spaces causes shear resistance decrease to some extent. Models have iron angles in compare with models have shear studs of the same stud spaces, have higher yield shear resistance and ultimate shear resistance. Angles connection way to steel plates are effective in increasing or decreasing ultimate shear strength.Wall with minimum reinforcement in comparison with the wall with no rebar has greater ductility and shear strength.
