N2 - When performing proof load tests, irreversible damage may occur. Guidelines for performing the test have been developed, which establish stop criteria to terminate the test before this happens. The stop criteria prescribed in the currently available codes are mainly designed for buildings, but load tests are also performed on bridges. This investigation compares the results from beams tested in the laboratory with stop criteria and analyzes their applicability on reinforced concrete bridges. The stop criteria from ACI 437.2M-13, the German guideline of the DAfStB, and a proposal developed byWerner Vos from TU Delft were evaluated. It was found that the DAfStB concrete strain stop criterion provided the most consistent results. The ACI stop criteria should only be applied if the ACI loading protocol is being followed. The deflection proposal by Vos, seems to be a reliable option, but further investigation needs to be done before it can be applied.
