Effect of Compressive Strength and Reinforcing Bar Diameter on Tensile and Cracking Aspects of Reinforced Concrete Prisms
The purpose of this research is to determine the impact of concrete compressive strength (concrete grade), bar diameter, and reinforcing ratio on the tensile (tensile stress and tension stiffening) and cracking (crack spacing) properties of reinforced concrete (R.C.) prisms under uniaxial tension. In this study, two different concrete grades (20 MPa and 40 MPa) and three different High Yield Strength Deformed (HYSD) steel bars (with a yield stress of 500 MPa) of 8-, 10-, and 12-mm diameter were used as tension chords in prismatic concrete members. From the experimental results, tensile stress and tension stiffening of the members increased as the compressive strength (grade of concrete) of the concrete increased. From this, tensile stresses of the concrete member are affected by the concrete’s compressive strength (grade of concrete), but not significantly by using different reinforcing bar diameters. According to cracking properties, crack spacings were influenced by the compressive strength of concrete and the reinforcing ratio (bar diameter). Since concrete’s compressive strength increased, crack spacing decreased. Also, as reinforcement ratio (bar diameter) increases, crack spacing decreases. Furthermore, the obtained crack spacings are consistent with Eurocode 2.
