Outline of Final Research Achievements |
High-Strength Steel Grade H-SA700A was developped by Steel Maker as Japanese Government Project. Many Researchers proposed the Weld-free Built-up Frame system made by the High-strength Steel which is kept a elastic resistance under severe earthquake ground motion. It means no damaged building structure after the severe earthquake. To use the High-Strength Steel member for building structre, it is required the effective joint thechnology. To solve the problem, I present the shear joint using half-moon-shaped bearing bolt as an effective fastener between high-strength steel members. Experimental studies were carried out to clarify the maximum strength of the bolted joint and the elastic stiffness of beam flange joint. Also, materially and geometrically non-linear finite element analyses were carried out to show the fundamental mechanical properties of the joint with half-moon shaped bearing bolts.
