A reasonable maintenance program made combining with the bridge deterioration model can effectively reduce the maintenance cost and improve the efficiency of maintenance. The bridge deterioration model is applied based on reliability index. With the bridge condition as boundary condition
andthe maintenance cost minimized in the whole service life as constraint condition
the optimal bridge maintenance strategyis obtained. Agenetic algorithm (GA) is applied to optimize the steel girder maintenance strategy of Haihuang Bridge. The result shows the feasibility of the method.
