VIBRATION CONTROL REINFORCING STRUCTURE

摘要

PROBLEM TO BE SOLVED: To improve the earthquake resisting performance of an existing unfair building. SOLUTION: According to a vibration control reinforcing structure for improving the earthquake resisting performance of the existing building 1 by fixing a vibration control frame 4 having vibration control dampers 2 incorporated therein to a skeleton of the existing building 1, corner portions of the vibration control frame 4 are substantially pin-connected to the skeleton of the existing building 1 by means of connecting members 8. Each connecting member 8 is formed of an open section steel product such as an H beam which is low in twisting rigidity relative to its shearing rigidity. Then, the vibration control frame 4 is fixed to the exterior of a plane of structure on the periphery of the existing building 1.
