Behavior of Reinforcement Concrete Beams Using Steel Strips as a Shear Reinforcements

摘要

An experimental and theoretical study on reinforced concrete beams using steel strip plates as a shear reinforcement instead of stirrups bars is presented in this paper. Five specimens with same dimensions and properties were used in this study. One of them has regular ties as shear reinforcements and is used as a reference beam. Other specimens used steel plates as shear reinforcements with an equivalent area of the regular ties of the reference beam. Four thicknesses of plates were used, 1mm 2mm, 3mm, and 4mm. The experimental results showed a good agreement in term of the ultimate load within the range of 99.86 -113.33% of the ultimate load of the reference beam. The steel strips work as a regular tie to control the cracks (number and width). The analytical result showed that there is a good agreement between the numerical results and the experimental results in the term.
