する。C. EFFECTS OF THE INVENTION Since the energy absorption device for structure of the present invention has the above-mentioned structure and acts, it has the following unique effects.
比較的小型の装置で、大きなエネルギー吸収特性を得
ることができ、建築物の壁構造への組込みが容易とな
る。It is possible to obtain a large energy absorption property with a relatively small device, and it is easy to incorporate it into a wall structure of a building.
構造が簡単であるので、加工手間が要せず、このため
製作費用の低減を図ることができる。Since the structure is simple, no labor is required for processing, and thus the manufacturing cost can be reduced.
鉛体の数及び配置を適宜に変えることにより、本装置
のエネルギー吸収特性を自由に選択することができ、設
計上の自由度が増大する。By appropriately changing the number and arrangement of the lead bodies, the energy absorption characteristics of this device can be freely selected, and the degree of freedom in design is increased.
鉛体はゴム弾性体内に四周を拘束されて封入されてい
るので、純せん断変形を受けるとともに、確実にエネル
ギー吸収作用を発揮し、かつ、その変形−荷重特性が明
確であることから合理的な設計が可能となる。Since the lead body is enclosed in a rubber elastic body with its four circumferences constrained, it undergoes pure shear deformation, exhibits a reliable energy absorption function, and its deformation-load characteristics are clear, so it is rational. Design becomes possible.
