Experimental and analytical study on shear capacity in steel fiber and stirrup RC beam

Abstract

In this study, strength and deformation behavior in steel fiber reinforced concrete (SFRC)

and stirrup RC beams, under bending-shear load, is investigated by analytical and

experimental methods. In the experimental test, optical measurement method was used. Analytically, a theoretical model for SFRC beams developed by the authors and FEM code was used. The structural response throughout the loading is captured and presented. Strength

comparison among SFRC, stirrup and control beam showed that SFRC beam has a better performance. A parametric study on fiber content and shear span to depth ratio variation characterized the strength enhancement in the fibrous beams. Analytical results obtained

using the theoretical model and FEM were in accord with the experimental results.
