AAR LABORATORY INVESTIGATION OF PRESTRESSED CONCRETE BOX BEAMS AND EPOXY SHEAR KEYS

Laboratory investigation is conducted on prestressed concrete box beams. The 1964 investigational work determines the static and repeated-load strength of box beams cast with regular mineral aggregate. Nine full-size beams are tested, some with a revised strand pattern, some without end blocks or a center diaphragm. Repeated and sustained loadings are conducted, and load ranges are measured. Conventional and through-voided beams are compared with the performance of lightweight beams, and ultimate and design loads are noted.
