VIBRATION PREVENTING STRUCTURE FOR INDIVIDUAL MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a vibration preventing structure for individual members forming a steel tower structure, which can damp various kinds of vibrations of the individual members without increasing materials or incurring increased wind load. ;SOLUTION: The steel tower structure is formed of a plurality of main column members which are vertically erected and serve as main members of the steel tower structure, and the plurality of individual members provided therefor in addition to the main column members in order to connect the main members to each other or strengthening the same. The vibration control structure for the individual members is constructed by connecting the individual members targeted for vibration prevention, by means of connecting members each having a vibration damping element. According to the structure, the connecting member functions to damp vibration amplitude of the two individual members targeted for vibration prevention, and therefore cracking and breakage of the individual members targeted for vibration prevention and joint portions due to fatigue thereof can be prevented. Further, the shape of each individual member targeted for vibration prevention is minimized, which leads to simplified structure of the joint portions.;COPYRIGHT: (C)2003,JPO
