| Abstract: | Finite element analysis is used to analyze reasonable elastic stiffness of longitudinal flexible restraints of the middle tower of Taizhou Bridge.The impact of elastic constraints on the main tower,the stiffening girder,cable,and dynamic characteristics is studied,The results show that setting elastic cable can effectively improve the mechanical properties for three-tower bridge. |
