Abstract:Durability based design of RC structures has gained great significance in recent decades and various mathematical models have been proposed. One of the famous models was proposed by fib. The effect of local conditions on the prediction of the models is one of the most important issues. Hence, regional investigations are necessary. The Persian Gulf is one of the most aggressive regions of the world. In this study, the fib model performance was evaluated by comparison with field measurements on some marine RC structures located in this region. The results show that the parameters in the fib model did not result in good agreement with some of field data. The model parameters were modified for application to this environment. In order to do this, a laboratory study was performed and nine different concrete mixtures with various percentages of silica fume were prepared. Evaluation of the modified model results shows that the modifications produced more reliable results than the original model for this environment.
