For technique hindrance, determining parameters for fluid viscous damper in bridge design is generally by nonlinear time history analysis of entire bridge model under earthquake.
由于技术原因，液体粘滞阻尼器在桥梁设计中的参数选取基本上是通过全桥模型的地震非线性时程分析得到的。

The total evolution index was induced and the FEM of material plastic damage model was supplied to simulate the nonlinear damage evolution of bridge structure subjected to the earthquake excitation.
Using the characteristic of integrated operational amplifier, an electric bridge circuit sensor without nonlinear error in its output voltage is designed.
