• Abstract:
  The behavior of the Texas Highway Department 54-in. prestressed concrete bridge beam under combined torsional and transverse loads was studied. Elastic theory and maximum tensile stress failure criterion were used to develop a theoretical failure envelope. Deflection, rotation and strain measurements were made on edge beams in two structures during placement of the deck. Load induced strains were of such small magnitude in comparison to other transient strain responses that the effective loads actually carried by the beam could not be determined with reasonable accuracy from the data.
