Effect of Type and Distribution of Shear Studs on the Behavior of Composite Steel-Concrete Shear Walls

In this research the in-plane shear behavior of composite steel-concrete shear walls was investigated by considering the following variables: steel plate thickness, the spacing between shear studs, the shape and type of the shear studs and consideration of the minimum reinforcement in the wall section. Several finite element models were analyzed and numerical results of two models were verified with available experimental results in the literature. Results showed that increasing the thickness of the steel plate increases the yield and ultimate shear strengths; moreover, increasing the spacing between shear studs reduces the shear resistance to some extent; furthermore, steel-plate composite (SC) walls with iron angles have higher yield and ultimate shear resistance than walls with studs; finally, the wall with the minimum reinforcement behaved better than the wall with no reinforcement in terms of ductility and shear strength.
