バーリング加工を活用した新しい機械的ずれ止めの開発

抄録

This research is development of new mechanical shear connector for joining steel and concrete which expected high-strength and high-stiffness. It is a steel plate using burring which is a kind of machining, and calls it "Burring shear connector". In order to examine the effectiveness of the burring steel plate, we performed a basic experiment (push-out test) which pushes steel with them outside from concrete block. The experimental parameter was the flange heights. A headed stud and a perfobond plate connector (PBL), which is the common type of shear connector, were also tested for the purpose of comparison. From the result of the experiment, the burring shear connector showed a good resistance performance as compared with the conventional mechanical shear connectors.
