Abstract: The influence of elastic deformations on compressive membrane action (dome effect) in restrained slabs is considered. The elastic-plastic circular slab is analyzed, using a flow-theory approach. The inplane and boundary flexibilities are lumped and an initial elastic deflection is assumed. The first part of the predicted load-deflection curve is compared with the results of a test series and reasonable agreement is found, especially with respect to the peak load.
