Abstract:
The Antonio Dovalí Jaime bridge is an important cable stayed bridge, located in the southeast of the Mexican Republic. The bridge has a total length of 1, 170 m and the main span is 288 m. It was open to traffic in 1984, and was the first cable-stayed bridge in Mexico. In order to assess the current state of the bridge an extensive program of non destructive tests was carried out; the field tests included measurements of stresses, a complete geometric survey of deformed configurations due to vehicle loads, and different series of ambient vibration measurements. The main results of the tests were: load-deformation relationships and dynamic properties (modal shapes, damping and frequencies) of first vibration modes. The results were employed to validate and improve a 3D finite element model of the bridge. The results obtained from FEM calculations were used to assess the actual state of the bridge.
