Experimental and analytical evaluation of shear strength in steel-fiber-reinforced concrete beams, indicating performance enhancement.

This research aims to assess how steel fibers improve the shear strength of reinforced concrete coupling beams.
Conducted experimental tests on RC coupling beams with steel fibers.
Performed nonlinear finite element analysis using DIANA FEA.
Executed a parametric study on the effect of fiber volume fractions.
Compared results with existing design equations for accuracy.
Fiber inclusion enhanced shear strength and modified crack angles.
Finite element analysis outcomes closely matched experimental results for strength and crack patterns.
Strength improved by up to 1% with higher fiber volume fractions.
Longitudinal reinforcement had a diminished influence on strength.
The softened strut-and-tie model provided accurate predictions compared to design equations.

Yoo et al. (2026) studied this question.
