The three-dimensional investigations of the stresses in the end-anchorage of post-tensioned concrete beams were carried out on six concrete end-blocks. Using the anchorage plate with different size of its' surface area, a concentric load was applied axially on the end surface of each test specimen and the tensile strain distributions along the center axis on each surface were measured by foil strain gauges. The approximate three-dimensional stress analysis around the end-anchorage was developed from the original that proposed by H. Sievers, and the measurements were discussed in comparison with theoretical strain distributions. The effects of the concentration of applied load upon the anchorage zone stress distributions were also investigated. The test results showed that the measured tensile strain distributions coincided fairly well with theoretical ones.
