Abstract EN
The strength of the composite deck slab depends mainly on the longitudinal shear transfer mechanism at the interface between steel and concrete.
The bond strength developed by the cement paste is weak and causes premature failure of composite deck slab.
This deficiency is effectively overcame by a shear transferring mechanism in the form of mechanical interlock through indentations, embossments, or fastening studs.
Development of embossment patterns requires an advanced technology which makes the deck profile expensive.
Fastening studs by welding weakens the joint strength and also escalates the cost.
The present investigation is attempted to arrive at a better, simple interface mechanism.
Three types of mechanical connector schemes are identified and investigated experimentally.
All of the three shear connector schemes exhibited full shear interaction with negligible slip.
The strength and stiffness of the composite slabs with shear connectors are superior about one and half time compared to these of the conventional reinforced concrete slabs and about twice compared to these of composite slabs without mechanical shear connectors.
The scheme2 and scheme3 shear connector mechanisms integrate deck webs and improve strength and stiffness of the deck, which can effectively reduce the cost of formworks and supports efficiently.
