MICRO VIBRATION CONTROL FRAME

摘要

PROBLEM TO BE SOLVED: To lower floor height and to reduce a construction cost besides suppressing vertical vibration while securing required rigidity. SOLUTION: This micro vibration control frame has a concrete floor 5 on the upper face of an upper chord member 4 of truss beam structure 1. A steel frame 8 of approximately U-shaped cross section opened on the upper side is used as a lower chord member 7 of the truss beam structure 1, and post-cast concrete 9 is filled in the steel frame 8.
