(1) After placing viscous dampers on our bridge formwork, the displacement of the end of the main beam has changed significantly, which shows that placing viscous dampers can effectively improve the anti expansion performance of the bridge structure and meet our requirements
(2) Attention should be paid to the placement of dampers: excessive differences in the stiffness of piers will lead to mutual disturbance of viscous dampers, which will reduce their anti expansion performance
(3) The effect of placing viscous dampers at different places is different. From our analysis results, in order to achieve optimal performance of viscous dampers, they should be placed at the abutment
