Also the response amplitude will be changed with the initial conditions due to the nonlinear properties of the cables.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 anew hybrid method for solving the cable-damper system is presented by combing the Newmark method and Pseudo-force technology. According to the known properties of the cable-damper system, the nonlinear transient responses are analyzed under all kinds of excitations. Based on the transient response, the control effectiveness of the visco-elastic dampers is further demonstrated.

For the COG joint subjected to thermal storage test at 80 oC for 1000hours, the resistance raises from 0.48 to 1.26Ω while in the sample, the resistance raises from 0.73 to 1.52Ω; all test results fit the reliability requirements. But the reason of increment is not only NCF material degradation cause, but also the bump is elastically. Therefore elastic bump resile caused the resistance to increase after pressing. Consequently I used another two samples which is not thermal aging compared to test samples, the results were show bump resistances increasing about 65%, its come form elastic bumps itself.

COG试片经过80oC约1000小时之后观察电阻上升情形，一片约从0.48Ω上升至1.26Ω另一片从0.73Ω到1.52Ω也符合可靠范围内，但是上升的原因不完全是胶材劣化导致，因为凸块本身具有弹性，所以在压合之后还会回弹造成电阻上升，因此会使用另两片未热时效的试片来比较，得知结果大概65％的电阻上升是来自本身具弹性导致。
