SEISMIC RESPONSE CONTROL STRUCTURE OF EXISTING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide a seismic response control structure of a structure capable of surely improving seismic response control performance with a simple structure. SOLUTION: This seismic response control structure K is composed of a seasonal structure 10 having an underground construction part 11 constructed in a range reaching the predetermined depth from the ground surface Ga, and the improved ground 20 formed by improving the ground around the underground construction part 11. The improved ground 20 is integrated with the underground construction part 11. A lower end part 21a of the improved ground 20 is formed in strength lower than a part 21b except for the lower end part. COPYRIGHT: (C)2005,JPO&NCIPI
