CONVERGENCE STUDY OF ITERATIVE METHODS APPLIED TO FINITE ELEMENT ANALYSIS OF REINFORCED CONCRETE

Results are presented of a study of convergence of a non-linear incremental-iterative finite element analysis of a typical reinforced concrete beam. It was found that eight increments of load, with no more than twenty iterations per increment, were sufficient to model the important behaviour characteristics of the member, as confirmed by comparison with experimental data. With respect to the overall performance at all stages of loading, including deflections, distribution of compressive stresses in the concrete, and tensile stress in the main reinforcement, very few iterations were required. The important contributions were obtained from the first one or two cycles.
