ACI-DAfStb database of shear tests on slender reinforced concrete beams without stirrups

Nearly all code provisions for the shear capacity of structural concrete members without shear reinforcement have been empirically derived and some were calibrated decades ago. Since then, a significant volume of new test data has been generated that can aid in understanding. To address this issue, a database of 439 shear test results had been created in 2003 that contained the data of beams without shear reinforcement subjected to point loads. The 2003 database was considerably expanded in recent years by a joint ACI-DAfStb (American Concrete Institute - Deutscher Ausschuss für Stahlbeton, German Committee for Structural Concrete) Group, with new test data including 40 tests on beams with uniformly distributed loads. The newly extended database now contains 784 tests that can be used for the evaluation of shear design provisions. A comparison of ACI 318-11 Eq. (11-3) with this extended database has revealed that current code provisions can be unconservative for large, lightly reinforced members and that the influences of important parameters are not adequately captured.
