摘要

In a column structure (10), a steel column (30) as a column member is joined to a base plate (16A) as a base member (16). The steel column (30) is composed of a web (30A) and a pair of flanges (30B) provided at both ends in the width direction thereof. One end side of the base plate (16A) is secured by a first anchor bolt (24) as a first anchor member. The other end side of the base plate (16A) is secured by a first anchor bolt (28) as a second anchor member, and the first anchor bolt (28) is formed to have a higher tensile strength than the first anchor bolt (24).
