阻尼系統被廣泛用於減少系統中之能量,因此降低結構於地震下之反應。然而,阻尼器不同之安裝機制和位置不易比較,所以Kasai提出三個彈簧模型,來探討八種阻尼系統之差別。
本研究以八種不同的阻尼系統來評估其消能效率和提出未來阻尼系統設計與發展之方針,使用SAP2000軟體以進行側推往覆載重分析來研究其消能效率。研究的參數為:(1)三種阻尼器(D1,D2,D3) (2)八種型式的阻尼系統(Case1~CaseB3) (3)四種不同樓層的結構(1,5,10,20層) (4)四種大小的平均樓層位移(2.5‰,5‰,7.5‰,15‰)。由這些參數計算等效阻尼了解各種阻尼系統在各種參數下的消能效率。
主要研究成果如下:
1. Kasai Model中構架的相對變位比αN愈大消能效果會愈好,以及阻尼系統的勁度Kbs愈大消能效果也會愈好
2. 阻尼器位置為水平置中的消能效果最好。
3. 阻尼器水平置放比垂直及傾斜置放的消能效果好。
4. 樓高的高度較低的阻尼器消能效果較佳。
5. 阻尼系統水平支撐跨度愈大消能愈好。
Damper systems have been widely used to reduce the dynamic energy in the system therefore reduce the seismic response of the structures. However, due to different mounting mechanism and location, it is difficult to compare different damper systems.Kasai’s model with three springs were proposed and used to study the differences among three damper systems.
This study intended to investigate eight different damper system to evaluate their energy dissipation efficiency and propose guidelines for future damper system design and development. SAP2000 software was used to apply cyclic push over testing on structures to study the efficiency of energy dissipation. The parameter studied are: (1) three type of damper (2) eight type of damper system (mounting mechanism) (3) four different story of structures (1,5,10,20) (4) four different story drift ratios (0.25%, 0.5%, 0.75%. 1.5%)
The results are:
1. In Kasai’s model, damper system with larger αN and larger Kbs tend to have larger energy dissipation.
2. The damper systems mounted at the center of the panel have the best energy dissipation.
3. The damper systems mounted at horizontal direction have better energy dissipation.
4. The damper systems mounted on shorter structures have better energy dissipation.
5. The damper system mounted with larger span have better energy dissipation.
