Abstract

This study reports on the results obtained in an experimental test programme carried out on 18 wide beams of 750 mm in width, 250 mm in depth and a 3 m free span, designed to fail by shear. From the tests, a clear influence of arrangement of vertical shear reinforcement, transversal spacing of stirrup legs and support width on the shear strength is found. The shear strength of the tested beams has been compared with the ones predicted by the codes ACI 318 and Eurocode 2 and several improvements to both codes are proposed in order to take such effects into account. Finally, some design recommendations about distribution of stirrups are included in this paper to optimise the vertical shear reinforcement effectiveness and prevent premature shear failures.
