Document Type: Journal Paper


The literature on compressive membrane action (dome effect) in restrained slabs is reviewed with emphasis on plastic analysis. The differences between the flow theory and deformation theory approaches are discussed. The example of the rigid-plastic restrained slab strip is used to show that deformation theory may lead to unrealistic predictions.
