| 中文摘要 | 本文旨在研究滑動式隔震結構受外力作用下之滑動--晃動行為。研究過程採不連 續元素方法進行數值模擬。文中首先提出模擬塊體碰撞接觸時決定不連續元素間接觸彈簧係 數之方法,以之應用於分析單自由度滑動結構純滑及剛體純晃行為,並與理論所得之解析解 比較,檢核不連續元素法數值分析之精確程度。再進而分析伴隨滑動之晃動反應。結果顯示 在滑動 -- 晃動諸多影響因素中,以結構高寬比對晃動行為影響最大。而摩擦界面性質,在 小幅晃動時,並無顯著影響。 |
| 英文摘要 | The paper presents a preliminary study of sliding-rocking behavior of sliding structures. The discontinuous deformation analysis method was adopted to simulate this behavior. This study provides a simple straight forward way to determine the stiffness of contact spring which used in-between blocks to simulate the contact. Analytical solutions from previous published researches are used to compare the answers obtained by the chosen method. It is found that the discontinuous deformation analysis method can provide answers with good accuracy. The numerical results reveal that the height-width ratio of structure is the major factor governing the structural motion for free rocking vibration, whereas the friction of sliding surface has very little influence on this. |
