Which tensile strength reduction happens when pre-tensioned concrete cracks?

💡 Explanation

Loss of prestress occurs because force redistribution from the steel to the concrete adjacent to the crack happens via elastic shortening. Therefore, the tensile capacity decreases, rather than changes in creep characteristics or changes in aggregate relationships across fracture surfaces.
