en Applications Applications پژوهشي Research In the current study two methods are evaluated for predicting the compressive strength of concrete containing metakaolin. Adaptive neuro-fuzzy inference system (ANFIS) model and stepwise regression (SR) model are developed as a reliable modeling method for simulating and predicting the compressive strength of concrete containing metakaolin at the different ages. The required data in training and testing state obtained from a reliable data base. Then, a comparison has been made between proposed ANFIS model and SR model to have an idea about the predictive power of these methods. adaptive neuro-fuzzy inference system (ANFIS), stepwise regression (SR), compressive strength of concrete, reliable modeling method, metakaolin. 251 272 http://ijoce.iust.ac.ir/browse.php?a_code=A-10-66-223&slc_lang=en&sid=1 Y.
