Abstract
A join structure comprises a box section column and spit T-section joined by a high strength bolt and a method secures a nut to an inside of the box section column. A Torque-Shear type high strength bolt is tightly tightened by a controlled tension and a joining method of a steel member uses that bolt. The join structure is comprised of a box section column, a split T-section attached to its outer surface, and a high strength bolt inserted from the outside of the split T-section and fastened with the nut. The nut is secured to the box section column by joining a sleeve secured to a washer formed integrally with the nut and a sleeve of a nut holding part from the outside of the column. The Torque-Shear type high strength bolt has a pintail for controlling the torque at its top.
