エネルギー吸収能に着目したスリット形状のボルト孔を有する高力ボルト摩擦接合継手

抄録

In this study, we verified the basic properties of high strength bolted friction joints with slits as the bolt holes to improve the energy absorption capacity from static loading tests and static analysis. The results showed that the coefficient of slip remained almost constant with increasing slip after the initial slip. It was also shown that the shape of the slit affects the resistance force after sliding. Furthermore, we propos ed a joint that amplifies the post slip resistance and elucidated its mechanism.
