Longitudinal shear strength prediction for steel-concrete composite slabs with additional reinforcement bars

Abstract This paper presents an experimental and analytical study of composite slabs with additional reinforcement bars. The analytical model is based on m-k method and is able to estimate the longitudinal shear capacity of composite slabs with additional reinforcement bars. A total of 11 simply supported specimens with different additional reinforcement rates and shear span length were tested. All slabs showed ductile longitudinal shear behavior. Composite slabs with additional reinforcement bars exhibited greater ductility and load capacity than corresponding specimens without additional reinforcement bars. The analytical model was verified against experimental data and showed good agreement with test results.
