Implication

Experimental investigation reveals how axial tension affects shear strength in steel fiber reinforced concrete beams, suggesting improvements for design practices.

Key Points

This study aims to investigate the shear behavior of steel fiber-reinforced concrete beams under axial tension and shear, addressing gaps in current design codes.
Conducted experimental tests on SFRC beams with varying axial tension-to-shear ratios and steel fiber volume fractions.
Examined beams with a constant shear span-to-depth ratio of 2.5 and different longitudinal reinforcement ratios.
Proposed a regression-based equation to estimate shear stress based on experimental data.
T/V ratios below 1.0 showed negligible influence on shear response.
Higher T/V ratios resulted in significant reductions in diagonal cracking load, ultimate shear strength, and stiffness.
The inclusion of steel fibers improved shear capacity and ductility, while increased longitudinal reinforcement enhanced crack control.
