TUNED MASS DAMPER
PROBLEM TO BE SOLVED: To provide a TMD [tuned mass damper] in which both a spring and a damper can follow under a smaller displacement than that of a weight member to cause their designs to become easy and at the same time a stopper function against the weight member can be attained.SOLUTION: There are provided a weight member 1 having a square shape as seen from a top plan view that is arranged to be movable in a horizontal direction on a floor surface 3 of a structure through slide bearings or roller bearings 2; springs 5a, 5b and dampers 6a, 6b arranged to be oblique in respect to the floor surface as seen from a front elevational view between the four side surfaces 4a, 4b of the weight member 1 and the floor surface 3. Each of the springs and the dampers is arranged at symmetrical positions in respect to center lines of opposite sides 1a, 1b of the weight member 1 as seen from the top plan view, upper ends are fixed to the side surfaces 4a, 4b and lower ends are movably connected to the floor surface 3 in such a direction as crossing with extending directions of the springs and dampers.SELECTED DRAWING: Figure 2
【課題】スプリングおよびダンパーが錘部材の変位よりも小さな変位によって追従することができ、よってこれらの設計が容易になるとともに、錘部材のストッパー機能も奏することが可能になるＴＭＤを提供する。【解決手段】構造物の床面３上に滑り支承または転がり支承２を介して水平方向に移動自在に設けられた平面視方形の錘部材１と、錘部材１の４側面４ａ、４ｂと床面３との間に正面視において床面に対して傾斜して設けられたスプリング５ａ、５ｂおよびダンパー６ａ、６ｂとを備え、スプリングおよびダンパーは、各々上記平面視において錘部材１の対辺１ａ、１ｂの中心線に対して対称となる位置に配置され、上端部が側面４ａ、４ｂに固定され、下端部がスプリングおよびダンパーの延在方向と交差する方向に移動自在に床面３側に連結されている。【選択図】図２
