Column structure and base member

摘要

In a column structure, a steel column having a web and flanges integrally provided to both sides in a width direction of the web is welded to a base plate. First anchor bolts and second anchor bolts are anchored in foundation concrete. The base plate is fixed to the first anchor bolts at an opposite side to the web with respect to the flanges, and fixed to the second anchor bolts at a web side with respect to the flanges. The load bearing ability of a column setup can therefore be efficiently exhibited, and a thickness dimension of the base plate can be reduced.
