Effect of Different Types of Shear Reinforcement on the Strength, Stiffness and Crack Resistance of Bending Reinforced Concrete Elements

Abstract

This article describes the effect of three different types of shear reinforcement on the strength, stiffness and crack resistance of bending reinforced concrete beams. This paper reports experimental data on the behavior of reinforced concrete beams, reinforced with different shear reinforcement. Tests were conducted on four reinforced concrete beams, one with stirrups and three with different types of shear lattice girder (truss) reinforcement. The behavior of the reinforced concrete beams is analyzed and supported with statistical evaluations. Conclusions are drawn, showing that the beams act differently under the action of the same subjected load, providing numerical data ensuring the effectiveness of the two types of shear reinforcement with respect to the standard widely used model (model with stirrups).
