There are a number of models for predicting concrete creep behaviour such as models proposed in RILEM - B3, EN 19921-1-:2004, SABS 0100-1; MC -10… The existence of these different models for concrete creep analysis is resulted from the dependence of creep characteristics on many factors, including internal factors and external factors. Each model is therefore suitable for a specific condition. This study aims to analyse the creep models of concrete given in some concrete standards. Characteristics and scope of application of each model were clarified. These models were then applied to calculate concrete creep based experimental results on long-term deformation of reinforced concrete column sample in Viet Nam. A method of determining concrete creep coefficients was also established in this study. Compare the concrete creep coefficient calculated from the above methods and the results of the experiment to select the expected model. The results show that models ACI 209-2008 and EN 1992-2004 were the most suitable ones for applying in Vietnamese conditions. We recommend using these models for creep analysis of concrete in Viet Nam and in tropical climate.
