Nummerical analysis of built-up GFRP composite beams

Abstract

This paper deals with the issue of built-up composite beams made of GFRP (Glass Fibre Reinforced Polymers). Numerical models were analysed using the finite element method by ANSYS software. The primary focus is on evaluating the influence of bolt spacing on the ultimate load-bearing capacity and mechanical behaviour of the beams. The study aims to identify key parameters affecting the mechanical behaviour of built-up GFRP composite beams and provide insights into the influence of bolt spacing.
