Yielding novel k-factor formula according to the aisc standard by machine learning

Abstract

The results of using machine learning via genetic programming (GP) to automatically generate novel effective length factor formula in accordance with AISC standard are presented in this article. The data points obtained from applying the numerical method equation solving for the transcendental equation for the effective length of the braced frame were fed into the machine learning algorithm. The the formula was compared to the AISC standard's numerical solution method for the equation. As a result, the error in the formula is negligible. Therefore, for greater convenience in practice, the the formula can completely replace the AISC standard's chart.
