Time-Dependent Reinforced Concrete Slab Deflections

Abstract
A finite element analysis to determine time-dependent deflections of reinforced concrete slabs, including the effects of cracking, creep, and shrinkage, is presented. The analysis employs a 16-degree-of-freedom layered rectangular plate bending element, and uses a numerical time integration scheme to evaluate creep and shrinkage strains determined from CEB parameters. The initial strain technique is used in the solution procedure. Predicted results are compared with the limited experimental results in the literature.
