| Outline of Final Research Achievements |
In this research, in order to realize the member connection structure of the recycling / reuse bridge which is easy to assemble / disassemble, the new main girder which combined the high strength bolted tensile joint and the friction joint proposed by the research representatives It aims at strengthening the connection structure and establishing its design method.
As a result of examining the influence of the difference in the structural details of the flange connection part on the joint strength and deformability, it was found that the structure attached vertically to the structure in which the stiffening rib of the flange connection part is mounted parallel to the main girder flange is larger It is clarified that the deformation amount of the strength and the maximum strength character increases and it becomes a more ductile failure mode. In addition, we proposed a bending strength calculation method with higher accuracy than conventional strength calculation method.
