  • Numerical study on slip and after-slip behavior of high strength bolted frictional joint with tight type filler extended toward the outside of splice plate

    Takai Toshikazu, Moriyama Hitoshi

    Journal of Structural Engineering, A  ( Japan Society of Civil Engineers )  66 ( 0 ) 521 - 528   2020.01  [Refereed]

     View Summary

    <p>If the thicknesses of connected plates in high strength bolted joint are different, filler plate is used to adjust the difference in thicknesses. The filler is extended in some cases to reduce the relative displacement between splice and connected plate. In Japanese design codes, the extended filler is usually adopted to bearing type bolted joint. Slip and after-slip behavior of the extended filler plate in frictional joint is not investigated. This study focuses on the extended filler. The behaviors are investigated by FEM analysis. This paper concludes that the influence of extension of filler in high strength bolted frictional joint is small to resistances such as slip load and yield load.</p>

  • Fundamental study on influence of the number of bolt rows of specimen of high strength bolted frictional joint on slip behavior and yield behavior of connected plate in tensile experiment

    Takai Toshikazu, Moriyama Hitoshi, Yamaguchi Takashi, Yamamoto Yuta

    Journal of Structural Engineering, A  ( Japan Society of Civil Engineers )  65 ( 0 ) 365 - 376   2019.01  [Refereed]

     View Summary

    <p>This study focuses on influence of the number of bolt rows of specimen in tensile experiment of high strength bolted frictional joint. Difference of constraint condition on side surface of the joint according to the number might affect to mechanical behavior such as slip and yield of the joint. FEM analysis has been carried out to evaluate the influence in these behaviors. Slip and yield load of single bolt row joint are almost same or smaller than those of a row of multi bolt row joint. This fact suggests that the result obtained by a specimen with single bolt row might be lower load and gives safety evaluation. This paper also indicates the mechanism causes the difference of the loads.</p>
