In order to better evaluate the residual shear capacity of existing concrete structures, such as multi-span concrete slab bridges, shear tests have been carried out on beams sawn from a bridge constructed in 1961. The test setup is designed to generate moment distributions of both simply supported and continuous structures. The test results are compared with numerical simulations and results derived from earlier tests done on similar specimens. The results show that other than the initial stiffness, the presence of existing cracks in concrete have a quite limited influence upon the inclined cracking load. The Eurocode formula is able to predict the inclined cracking load with a reasonably accuracy.
