A methodology for evaluating the fracture width of a notched RC multiple-layer flat slab under cyclic loading.

ABSTRACT: This paper introduces an innovative method for assessing crack width in notched reinforced concrete (RC) slabs under cyclic loads, considering both precast and in-situ layers in composite slab configurations. The study addresses gaps in current research on crack behaviour under fatigue, providing a method that evaluates stress distribution and crack spacing around flexural notches. By employing empirical curvature values and comparing predicted crack widths with experimental data and fracture mechanics standards, this approach accounts effectively for tension stiffening effects. The results reveal that composite slabs exhibit controlled crack propagation and improved resistance under cyclic loading, demonstrating the effectiveness of the composite action. This model not only bridges the ga
