Abstract:
A numerical model is developed to predict the splitting and cracking stresses caused by bond action between the deformed bars and surrounding concrete of concrete specimens reinforced in both directions. This model considers the influence of confinement provided by the tensile strength of concrete cover and the transverse reinforcing bars perpendicular to the direction of the splitting cracks’ propagation. Furthermore, this investigation is extended to provide design equations for evaluating the tensile strength of normal- and high-strength reinforced concrete (RC) plates subjected to a biaxial loading condition, considering the secondary effect of the splitting stress.
The comparison between the predicted results of bond stresses, the concrete tensile strength, and the corresponding measured data obtained experimentally reveals a favorable agreement.
