At this time, special sliding bearings are applied to the superstructure, and if horizontal force acts on the structure on the foundation side, radial,
Or cross-shaped (cross-shaped) steel materials placed horizontally in a + shape act as a damper and absorb vibration energy. Figure 1 shows the cross section and side view, and Figure 2.3 shows this mechanism. This is a diagram viewed from above.A large horizontal force causes radial or cross-shaped (+-shaped)
If a horizontally placed steel member yields, this part should be removed and replaced with a new one in preparation for the next horizontal force.

A special sliding bearing 9 is installed on the lower foundation girder 7. A frame 8 is installed, and a special sliding bearing 9 is installed. can.
構造物に水平力が作用した場合この装置により振動エネ
ルギーを吸収し、構造物の安全を確保することができる
。この装置は鋼材を水平に配置することにより同一平面
上で力を処理することができ安定性がある。When a horizontal force acts on a structure, this device can absorb vibration energy and ensure the safety of the structure. This device has stability because it can handle forces on the same plane by placing the steel members horizontally.
第２図に示した形状のものは水平力が作用した場合、鋼
材の長さに変化が生じ特に良好な復元力が得られる。In the case of the shape shown in FIG. 2, when a horizontal force is applied, the length of the steel material changes and a particularly good restoring force can be obtained.
