Abstract

In recent years, methods of evaluating the crack width in concrete slabs and those of the stress in reinforcing bars at intermediate supports in continuous composite bridges have been proposed. They are applicable to evaluation of the crack width and stress in reinforcing bars at the stabilized crack state (fully cracked state). In many actual bridges, however, the initial crack state has been observed under the hogging bending moment. In this paper, employing formulas recommended in a current method and CEB/FIP-90, a method of evaluating the crack width and stress in reinforcing bars is proposed, in which the crack width and stress in reinforcing bars for both initial and stabilized crack states can be dealt with.
