摘要

PROBLEM TO BE SOLVED: To secure an excellent structure performance capable of being applied to a medium-low story building, in a simple and low-cost structure.SOLUTION: A column leg pin structure 10 includes an SRC column 1 of a steel reinforcement concrete structure in which a first steel column 11 protruding toward a base beam side and a second steel column 12 jointed to an upper end of the first steel column 11 through a column joint part 14 are embedded in column concrete 13. The SRC column 1 is connected to a base beam 2 of a concrete structure. The column leg pin structure 10 is provided in which the first steel column 11 protrudes downward from a column concrete lower end surface 13a of the SRC column 1, and in a state in which a protruding portion of the first steel column 11 is embedded in the base beam 2, a clearance C is provided between the column concrete lower end surface 13a and an upper surface 2a of the base beam 2.
