Strength tests performed on three sizes of precast concrete portal culverts from two different manufacturers indicated that the SABS 0100 code requirements for shear strength for pinned support portal culverts were conservative. Some of the pinned support culverts exhibited adequate shear strength to meet the design requirements. Shear failures, however, were brittle and the results indicated that changes in detailing might be required.
