Behaviour of reinforced concrete slabs strengthened by concrete overlays
View through CrossRef
This paper discusses the influence of three factors, the distribution of shear connectors, the concrete compressive strength, addition of new concrete thickness on the behavior of one-way composite pre-slabs. The experimental program involved nine tests to study flexure and cracking behaviour of reinforced concrete slabs strengthened with cast in- place new concrete layer. Three of them were reference monolithic slabs and the remaining six slabs were composite pre-slabs composed of two layers with different distributions of shear connectors according to shear force distribution. All slabs were tested under two line loads. The strengthening with cast in-place new concrete layer significantly increases the strength capacity of reinforced concrete (RC) slabs.
