Abstract

This paper presents an investigation of the nonlinear response of reinforced concrete slabs that rest on tensionless elastic foundations. A computational model based on the finite element method is employed. The stiffness matrix for the plate element is developed using a layered approach, in conjunction with the appropriate stress-strain relations and failure criterion. A supplementary stiffness matrix is used to model the effect of the tensionless elastic foundation. The model is used to investigate the loss of contact between reinforced concrete slabs and the underlying elastic foundation in the elastic as well as the inelastic range. Results are presented for two slabs with different steel reinforcement areas to examine the effect of the reinforcement ratio on the contact zone and the failure loads and modes.
