Abstract : This report covers the fabricating, prestressing, grouting and long-time loading of 22 post-tensioned prestressed concrete I-beams. These 42foot members were subjected to loads varying in magnitude from dead load only to dead load plus 1.5 design live loads for periods of 74 to 80 months. The report contains data on the properties of the beam materials, shrinkage prior to prestressing, tendon elongations and longtime creep and deflection of the beams due to loads of various magnitudes.
