Bending-shear test results of prestressed high strength concrete piles are introduced in this paper, for the purpose of reproduction of the damage aspect by the Off-Miyagi prefecture earthquake in 1978. Two kinds of test type are selected. The first is bending-shear test by simple beam method. Final failure type is investigated for each case of shear span ratio 3.33 and 2.22. The second is the newly proposed method, i, e., concentrated load is applied at the near part of the center of pile supported by the fixed end and the other pinned end. This load system is expected to produce simulated bending moment distribution of pile in the ground by horizontal load. Three different types of connection between pile and footing are used as the test specimens. Shear span ratio is 2.24.
