| Outline of Final Research Achievements |
In the column bases of the steel structure building, the embedded column base is easy to secure the most proof strength and rigidity, and there are few cases of earthquake damage. However, in the case of an outer embedded column base, if the thickness of the front cover concrete is small, destruction of the punching shear may occur. Several reinforcement methods for this destruction have been proposed, but the generality of the strength evaluation formula of the punching shear fracture resistance including the effect of the reinforcement around the steel column has not been established.
In this study, we carried out the loading experiments on the outer embedded column base, examined the stress transfer mechanism at the connection, and proposed the strength evaluation method considering the effect of the reinforcement.
