For the purpose of obtaining the three-dimensional stress distribution at the anchorage zone of post-tensioned prestressed concrete members, preliminary two-dimensional investigation has been carried out on 5 end blocks of rectangular post-tensioned prestressed concrete beams. Using the anchorage plates with different widths, a concentric load was applied axially on the end surface of each test specimen, and the tensile stress distributions along the center axis on each surface were measured by SR-4 wire strain gauge. Test results showed that the measured tensile stress distrebution in concrete end blocks coincided fairy well with the theoretical one given by F. Bleich and deviated strongly from the approximate distribution given by Y. Guyon, which are generally used in designing the tensile reinforcement in anchorage zone of post-tensioned prestressed concrete members.
