Abstract
The use of high strength reinforcement in reinforced concrete members is partly limited by the crack width which can be allowod without danger of corrosion of the reinfocement. In this paper, the stress distributions in the portion of reinforced concrete beams located between two main flexural cracks are analyzed by the finite element method. These stress distributions have been calculated approximately by assuming that the concrete behaves as an elastic material and the reinforcing bar as an reinforcing bar as an elastic spring. In addition to the above assumptions, the mechanical model of bond between the concrete and the reinforcing bar is introduced in the anaritical calculation. On the basis of numerical solution, the method for the calculation of the maximum crack spacing and the maximum crack width is described. The calculated crack spacing and crack width are compared with the experimental results.
