Abstract:The progress in structure condition assessment is briefly reviewed, and based on this, the general methods of bridge condition assessment are introduced and compared, including Monte Carlo mthod and analytical hierarchy process, etc. Combined with the introduction to the condition assessment system on Runyang Bridge which is the longest suspension bridge in China and Sutong Bridge which is the longest cable-stayed bridge in the world, the function and its constitution of this system are discussed in detail. Finally, the main problems in probability analysis and the development of condition assessment are presented.
Keywords:condition assessment  health monitoring  structure probability
