Abstract
In a column structure, a base member is fixed onto a foundation by mortar, serving as a fixing member. First and second anchor bolts are employed as anchor members for fixing the base member. A steel column, serving as a column member in which flanges are integrally formed at both sides in a width direction of a web, is joined to the upper side of the base member. A shear resistance member is provided to a lower portion of the web, so as to be buried at least in the mortar. The shear strength of the column structure is raised by the shear resistance member.
