ANFIS BASED EVALUATION OF CONCRETE BEAMS WITH HYBRID CONFINEMENT

An attempt has been made in this paper to evaluate the performance of internally confined concrete beams with externally bonded fibre reinforced polymer laminates using ANFIS software. Compressive strength, yield strength, thickness of FRP, spacing of stirrups, tensile strength of FRP have been considered as the input parameters. First crack load, deflection at first crack load, yield load, deflection at yield load, ultimate load, deflection at ultimate load, deflection ductility, energy ductility, crack width has been treated as the target parameters. All the performance parameters have been predicted using gaussmf membership function out of the eight membership functions available in the ANFIS software. The performance parameters such as first crack load, deflection at first crack load, yield load, deflection at yield load, ultimate load, deflection at ultimate load, deflection ductility, energy ductility, crack width predicted using the ANFIS tool correlated well with the performance parameters obtained through experiments.
