Abstract:
General design data are given for four prestressed concrete highway bridges and two prestressed concrete railroad bridges, built at the U. S. Air Force Academy site. One full size 120-ft girder was tested in two stages, leading to final destruction, in order to check workmanship and validity of design assumptions. First the girder alone was loaded to cracking. Then a 9 ft wide and 7 in. thick slab was cast to form a composite unit which was loaded to failure. Results of both tests are discussed in detail.
