Abstract

In a bridge, flexure cracks can be spotted and their mechanical consequences estimated through the automatically measured redistribution of curvature variations under convenient loading and a quick chain application of the classical expression for bending moment in beams. The residual flexural stiffnesses are thus obtained and introduced into a specific structural analysis program to define the new statical system of the bridge. More realistic stresses can then be predicted for any given live loads and at any time intervals.
