Numerical Analysis on Flexural Strength of Composite Slab with Inverted U-Shaped Shear Connector

Steel–concrete composite slab utilizes the advantages of steel as well as concrete and also reduces the overall dead loads. Flexural failure, vertical shear failure and longitudinal shear failure are the three major failure modes of a composite slab. The most prominent mode of failure is the longitudinal shear failure which is denoted by the horizontal slip between steel sheet and the concrete layer. In order to reduce slip, inverter U shaped shear connectors are introduced. This study focuses to improve the flexural strength of composite slab by using High-Performance Concrete (HPC), which also incorporated the usage of construction and demolition waste as recycled coarse aggregates. Numerical study is conducted on simply supported one-way slab. Parameters varied and studied are different configurations of inverted U-shaped connectors and overall depth of the slab. The composite slab with inverted U-shaped connector is expected to have more load carrying capacity and flexural strength than composite slab with shear studs.
