| Abstract: | Damage determination of Hangzhou Bay Sea - Crossing Bridge offshore platforms is conducted through the present theoretic results. Analyzing the dynamical characteristic changes of the prototype structure and the damage structure by finite element method, it can be judged that the structure is damaged or not. The article achieves the numerical simulation analysis of the damaged structure taking the Hangzhou Bay Sea - Crossing Bridge as an example. |
