Ultimate load in beam column joints under opening moment using genetic algorithm

Abstract

Genetic Programming (GP) is an independent domain, an approach for problem-solving which evolved the computer programs for finding solutions to the problems. The study was carried out by performing the experiments and validation of obtained results under opening moments was done analytically using finite element modelling (FEM) of fibrous and non-fibrous concrete corner joints. Genetic Programming is used to generate the mathematical formula. Fibers like flat crimped-type steel fibers, hooked steel fibers and straight steel fibers with aspect ratio (AR) 30 & 50 and four volume fraction 0.5%, 1.00%, 1.50% and 1.75% have been used. Ultimate load is calculated using GP by generating a mathematical model for various types of fibers and compared with experimental values obtained which proved to be in the closed proximity.
