THE MODELLING OF THE EFFECTS OF AAR EXPANSION ON REINFORCED CONCRETE MEMBERS

It has been shown that AAR induced expansion can be reduced significantly by the application of compressive stress. The effect of this reduction in expansion has not been previously included in the analysis of AAR specimens. This paper describes an incremental analysis for symmetric sections which takes account of this phenomenon and compares the theoretical results with those obtained in tests. An incremental numerical analysis based on similar assumptions is then described that can be used for general sections. The results from this analysis are also compared with experimental data.
