Abstract：
95 test samples of embedded steel bar are researched by using pull-out method, and consideration is made to the influences of concrete strength, diameter of embedded steel bar, burial depth, hole size, thickness of protection layer, shape of steel bar, etc., on the bond anchorage performance of embedded steel bar. The test results indicate that the damages of embedded steel bar are mainly divided into five types, each of which is analyzed on the aspect of mechanism. Bond force calculation formula involving many influencing factors is given and some important problems which may be encountered during practical application are discussed.
