This paper presents results of an experimental investigation into the load-deflection behaviour of restrained reinforced concrete slab strips subjected to uniformly distributed loads beyond the yield load. A method incorporating compressive membrane action is proposed to predict the behaviour. Results indicate that the proposed method can predict the actual trends for certain scenarios. Previously reported methods have been studied and the results compared with those from the current work.
