A study on Evaluation of Anchorage Capacity of Headed bars in Steel Fiber Reinforced Concrete Exterior Beam-Column Joint
In the case of an exterior beam-column joint, failure of the joint may occur if the sufficient development length satisfying the criterion is not satisfied.Although there is a method of using straight bars to anchorage the joints, hooked bars are used to reduce the development length.However, it is difficult to construct the steel when using hooked bars due to the overpopulation of rebar.To address this, the use of headed bars reduces the excess concentration and can also reduce the developed length by about 20% In addition, steel fiber reinforced concrete can be used to improve the tensile strength of concrete, thereby improving the anchorage performance of the expanded headed bars.Therefore, in this study, the repeated force test of the exterior beam-column joint was performed to evaluate the Anchorage performance of headed bars according to the steel fiber reinforcement (0%, 1%).Through the experiment, it was found that the Anchorage performance of the specimen reinforced with steel fiber was improved, and that the steel fiber affected the Anchorage performance of headed bars.
