Strength calculation of reinforced concrete beam reinforced with glass fibers

Abstract

In this study, the theoretical load-bearing capacity of fiber-reinforced concrete beams was analyzed by
introducing glass fibers with a length of 40 mm into the concrete matrix through dispersed reinforcement.
The theoretical calculations showed that when the fiber content ranges from 0.1% to 0.5%, the maximum
load-bearing capacity of the beams increases significantly. The highest efficiency was observed in fiberreinforced
concrete beams containing 0.2% glass fibers. The obtained results are consistent with existing
scientific literature and theoretically confirm the effectiveness of dispersed reinforcement. This study
contributes to improving structural efficiency, determining the optimal fiber content, and analyzing the
load-bearing behavior of glass fiber-reinforced concrete beams. Comparing the theoretical results with
experimental tests can further enhance the effectiveness of future research.
