Abstract
In this paper, we conducted tensile loading tests, with grid-bolted connections loaded perpendicular to the grain. From these tests, we would appear the relationship with the visual fracture characteristic, load-disp-behaviors and ductile factor coded in 2006 of Japanese design methods.
As a result, the fracture characteristic is almost in brittle and we could see linear behavior in a diagram. We could show fracture information of the bolted connections graded on JC.
