Outline of Final Research Achievements |
Column-bases are generally designed to consider a bending moment and an axial force, and it is clear that the axial force affects strength and stiffness of anchor-bolt-yield-type exposed column-bases. The collumn-base with a brace is acted by a strong axial-force and a strong shearing force, then it can be destroyed by excessive shearing force. Therefore, a cyclic loading test on a braced frame with weak column-base is carried out to clarify shearing fracture behavior of the column-base.
