Parametric Study of Exterior Shear Wall–Floor Slab Connections

Abstract
Experimental investigation on the effect of geometric parameters on the performance of exterior shear wall–floor slab joints subjected to cyclic loading is presented. A prototype building situated at Chennai, India was analyzed and estimated the force components in the exterior shear wall–slab joint. The force components and the dimensions were scaled down for 1/4th model following Cauchy’s law of similitude. Experimental investigations were carried out on eight numbers of 1/4th scaled models. The loading was applied at the end of the slab. The parameters considered are (1) ratio of height of shear wall and the effective width of the slab (), (2) ratio of thickness of slab to shear wall (), and (3) development length of reinforcing bars. The experimental observations were analyzed to arrive at optimum values of the height of shear wall (), effective width of slab (), thickness of shear wall (), thickness of slab (), and development length (). Numerical investigations were employed to compare the experimental results using the finite element software ANSYS. Good correlation was found between finite element analysis and experimental results.
