Ultimate strength of shallowly embedded anchor bolts under cyclic loading (Part.2 Test results of bonded anchors and estimation of ultimate strength)

摘要

In this study, in order to investigate the influence of cyclicloading on ultimate strength of shallowly embedded anchorbolts, cyclic loading tests of specimens with headed anchors andthose with bonded anchors were conducted. Conclusionsobtained in this study is listed as follows.In the case of headed anchor, influence of cyclic loading onultimate strength determined by concrete cone failure was notobserved. In the case of loading angle less than 45°, under cyclicloading, failure mode changed to anchor bolt fracture andultimate strength decreases comparing with that of undermonotonic loading.
