STUDY OF AXIAL BEARING CAPACITY OF SQUARE CONCRETE COLUMNS CONFINED WITH CARBON FIBER REINFORCED PLASTIC

square concrete columns confined with Carbon Fiber Reinforced Plastic (CFRP) under axial compression were tested. Finite element analysis was performed and a calculating model was presented to predict the ultimate strength of square Concrete Columns Confined with Carbon Fiber Reinforced Plastic. Two new methods for calculating bearing capacity of CFRP-confined columns are put forward. The results of both methods are in good agreement with the experimental data. The results can serve as reference to engineering application.
