| Abstract: |
High-strength frictional bolted joints is a usual connecting method of steel members at a construction site. Epoxy putty is also used to adjust the unevenness of corroded member’s surface in a repair with bolted connections. Thus, the repair is often conducted by hybrid joint with epoxy adhesives and high-strength bolts. The conversion to hybrid joints is also effective in terms of the performance enhancement. Therefore, this paper surveys experimental data of the hybrid joints in Japan to summarize essential pieces of information. Surveyed results show that the relationships between the average shear strength of hybrid joints and average contact pressure on the faying surface indicates a strong correlation. Therefore, hybrid joints have the strength characteristic of adhesive joints rather than frictional bolted joints. Moreover, approximate equations which can evaluate the peeing resistance of the joint composed of several bolts was proposed. |
