柱継手の塑性変形を許容した鉄骨柱脚の力学性能(建築学科)

Abstract

In this report, a method of construction that the plastic deformation of a column joint and only the elastic deformation of a column base are allowed is proposed. In consideration of restoration and structural stability, this column joint by splice plates allowed the plastic deformation is set up on the floor slab as a kind of support. From the test result under a cyclic lateral load with a constant axial load, the mechanical performance of this column joint is roughly verified, and structural problems in this method of construction are extracted. To contribute to the improvement of the structural design method of the steel structure, the questionnaire survey of the fabrication in Kyushu was executed.
