A New Fastener using Half-Moon Shaped Bolts for High-Strength Steel Member Part 6 Cyclic Loading Test on Beam Joint using Half-Moon-Shaped Bolt for High Strength members

We present the beamjoint using half-moon-shaped bearing bolt as an effective fastener between high-strength steel members. Experimental studies were carried out to clarify the elastic stiffness of beam flange joint. This paper shows capabilities of presented bolts. Obtained result was summarized as follows. In cyclic loading , the half-moon-shaped bolt to has sufficient flexural rigidity with the same that of as ordinary friction. Also, the half-moon-shaped bolts always penetrate the connected steel platesso as to fill up a hole. Hence, the present beam joint maintains constant stiffness under a large number of pulsating cyclic loadings.
