In this study, series of experimental tests on anchorage of deformed bars are conducted. The deformed bars are supposed to be used for shear reinforcement of hollow concrete encased steel (SRC) bridge column. Three types of anchorage method, hook, hook with dowel bar and mechanical nut with small flange, are prepared. As a result of high stress cyclic and static pull-out tests with nine test specimens, it is verified that crack width have much effect on anchoring strength in hook type.
