Simplified design of composite slabs using slip block test

Abstract

Steel-concrete composite slabs are a structurally efficient combination of constituents as they exploit the tensile resistance of the steel and compressive resistance of the concrete in an effective manner. Shear connection between the profiled steel sheet and concrete slab plays an important role in the design of these slabs. The verifications that are required for the design are long and complicated. Current design methods found in standards and guidelines rely on the results of costly and time-consuming large-scale laboratory tests. In this paper, a simplified approach for the design of composite slabs is proposed. This approach utilizes the results of the slip block test with a simple calculation model to obtain the moment of resistance based on the partial interaction method of composite slab governed by horizontal shear resistance. The results obtained using this approach are verified by comparison with the results based on the m-k test method. Copyright © 2005 Japan Concrete Institute.
