  1. Taking the bending stiffness, cable sag and cable inclination into consideration, the space vibration control of the cables using the visco - elastic dampers in cable - stayed bridges is investigated by joining the center difference method and the state space strategy. both the maximum modal damping ration and the optimal damper size are obtained, then the practical suggestions are proposed for the design of the dampers. the space nonlinear vibration equations of the cable - damper system are derived, and a new hybrid method for solving the cable - damper system is presented by combing the newmark method and pseudo - force technology

    綜合考慮了拉索抗彎剛度、垂度的影響,研究了粘彈性阻尼器斜拉橋拉索的空間振動控制,聯合中差分方法及狀態空間法,得出了拉索麵內、外振動各階模態可能達到的最大阻尼比及應的最優阻尼器系數,並斜拉橋拉索的阻尼器設計提出了參考建議:考慮拉索抗彎剛度、垂度及幾何非線性,導出了索-阻尼器系統的空間振動非線性方程組,結合newmark方法及偽力( pseudo - force )方法,創新地提出了求解非線性方程組的雜交方法,根據拉索-阻尼器系統的阻尼特性,在各種荷載作用下,索-阻尼器系統的非線性態振動響應進行了研究,從系統響應的角度更加直接地驗證了阻尼器的控制效果。
