The Experiment Study On Bonded Anchor Behavior Of Planted Bar And Reliability Analysis

In this paper, on the foundation of synthesizing engineering practice and study result of planted bar technique by chemistry glue on the domestic and international, embedded experiment study and theories analysis are done about bonded anchor behavior of chemistry planted bar anchorage behaviorIn this paper, the experimental results of 32 pulling resistance test(meiya Z3530) are given , considering some factors to affect bonded anchor behavior of chemistry planted bar such as the strength of concrete anchorage lengths diameter of steel bar and holes thickness of the protecting layer confecting circumstance of the hoop bar and quantity of construction especially which is very easy to be neglected and so on, and bonded anchor mechanism failure mode load carrying capacity and slide behavior are analyzed in-depth.The calculation formulas of loading capacity are deduced by the formula of average bond strength that is concluded from experiment results. Then based on reliability analysis of anchorage length, design formula and table for anchorage length with reliability guarantee that are suitable to every kind of condition are given. And the suggestion on design construction and supervise of planted bar are brought up.
