COMPUTER EXPERIMENTS WITH REINFORCED CONCRETE SLABS

The in-service behaviour of structural concrete slabs is complicated by the non-linear, inelastic and time - dependent nature of concrete. Little is known of the effects of time on slab deformations, extent of cracking and redistribution of moments. To study these effects analytically, a non-linear, finite element, slab simulation model which accounts for the dominant sources of material non-linearity was developed. The model has been shown to accurately predict both short-term and long-term behaviour of a wide variety of reinforced and prestressed concrete slabs and beams. In this report, an analytical investigation of the effects of various parameters on the service - load performance of reinforced concrete slabs is described and results from controlled parametric, computer experiments with several slab types are presented. Parameters, which are in practice coupled and confounded, are uncoupled and examined separately in order to gain a clearer picture of the mechanisms of structural behaviour. (Author/TRRL)
