YIELD PREDETERMINED-REGION SURROUNDING STRUCTURE OF SCREW REINFORCEMENT AND MATERIAL-END FIXING STRUCTURE OF COMPONENT IN REINFORCED CONCRETE BUILDING

PROBLEM TO BE SOLVED: To reduce damages of columns and beams in the case of an earthquake in a reinforced concrete building. SOLUTION: Screw reinforcements 21 and 22 for a foundation 1 (a base section) and the column 2 (a component) are connected by a cylinder 10. The cylinder 10 is arranged at the lower end section of the column 2. The screw reinforcement 21 on the foundation 1 side is extended from the material-end place E of the column 2 to an upper section, and screwed to a screwing section 11 for the cylinder 10, and a site surrounded by a sleeve section 12 for the cylinder 10 functions as a yield predetermined region Y. When a yield is generated in the yield predetermined region Y, an effect on the concrete 2a of the column 2 can be reduced by the sleeve section 12 for the cylinder 10, and the damage of concrete can be lowered.
