The main aim of the study was to perform selection procedure in order to find
the optimal predictors for the shear strength of fibre reinforced polymers
(FRP) used as internal reinforcement for reinforced concrete (RC) beams. The
procedure was performed by adaptive neuro fuzzy inference system (ANFIS) and
all available parameters are included. The ANFIS model could be used as
simplification of the shear strength analysis of the FRP-RC beams. MATLAB
software was used for the ANFIS application for the shear strength
prediction of the FRP-RC beams. The results from the searching procedure
indicated that ?beam width? and ?effective depth? form the optimal
combination of two input attributes or two predictors for the shear strength
prediction of the FRP-RC beams. This selected two predictors could be used
effectively to estimate the strength of the FRP-RC beams.
