A research team consisting of Professor Dr. Mushtaq Sadiq Radi (Civil Engineering Department – University of Karbala), Assistant Professor Dr. Iqbal Naim Korkis (Civil Engineering Department – Catholic University in Erbil) and Professor Dr. Maan Salman Hassan (Civil Engineering Department – University of Technology) has published a scientific research titled : (Analytical analysis of design-oriented models for forecasting the performance of CFRP-confined corrosion-affected concrete columns);
At (Construction and Building Materials) the journal categorized under first quarter rank and high impact factor.
The research includes a practical study of the use of carbon fiber-reinforced polymers in strengthening the reinforced concrete columns exposed to rust. Where the study included pouring 22 reinforced concrete columns and conducting rust in the reinforcement using the accelerated rust method with several levels of rust, then carrying out the reinforcement process with polymers reinforced with carbon fibers and several layers, and then testing the compression performance of the columns.
In addition to the practical aspect, the research included a theoretical study to assess the performance of short reinforced concrete columns subject to rust and coated with carbon fiber reinforced polymers. Based on the practical results, mathematical models (models) for the design were proposed for the purpose of predicting the performance of the columns (resistance and strain). There was good agreement between the predicted performance and the practical actual performance of CFRP columns. Where the error measures (root mean square error and mean absolute error) of the proposed models for estimating the compressive strength and strain were less than 10%. The mathematical models suggested by previous research and used in the current study are not suitable for predicting the performance of reinforced concrete columns under study that are subject to rust and coated with carbon fiber reinforced polymers because they gave an exaggerated prediction for the coated columns.
