千鳥配置高カボルト摩擦接合部のすべり耐力に関する研究

Abstract

This paper examines the slip strength of high strength zigzag bolted connections with base plate and splice plate material plasticity by monotonic loading. The loading experiment which made the number of bolts, base plate thickness, splice plate thickness is conducted. Slip behavior of zigzag bolted connections is compared with slip behavior of one sequence bolted connections. As a result, it is clear that, using zigzag arrangement, bolt axial force is early drawn out and an apparent friction coefficient is decreased. The slip strength model of one sequence bolted connection is applied at the slip strength of zigzag bolted connections.
