LOW HEIGHT LONG PERIOD PENDULUM DAMPING EQUIPMENT FOR TALL BUILDINGS

摘要

A long period pendulum damping equipment having right and left pair of longer rods (1,1), right and left pair of shorter rods (2,2) and a tie beam (5) connecting these longer rods and shorter rods one another, in which a tilt angle interlocking means (4a,4b) of both rods installed at right and left end portions of the tie beam, respectively, and keeping the tilt angle in one direction of the longer rod with respect to a vertical line always equal to the tilt angle in another direction of the shorter rod or certain ratio times thereof is provided, and a long period is provided and an installation space is made small while making the overall height low by pivoting a weight (6) to either one of the longer or shorter rod.
