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

Abstract

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.
