【 摘 要 】

This paper makes an overview on the domestic research on the steel column shear capacity in detail. On such basis, in accordance with the 4th theory of strength and the flexural vibration of straight bar, it makes theoretical analysis on the shear-bearing capacity of the steel column foot with the shear key and without the shear key respectively. It proposes the methods for calculating the shear-bearing capacity of steel column foot under two situations. It suggests that Code for Design of Steel Structures should raise the separation point of exposed steel column foot, which would reduce the construction difficulty of the exposed steel column foot, shorten the construction period, improve the construction quality and provide certain theoretical references for the design and research on the steel column foot.
