RESEARCH ABOUT BRIDGE LOAD MODELS BASED ON STRUCTURAL HEALTH MONITOR SYSTEM
As the foundation of the Life-Cycle design, the load models of bridge for reliability evaluation are discussed in this paper. The models of vehicle load included the vehicle load probabilistic model and the extreme distribution of the vehicle load are established based on the database of structural health monitoring system of the Binzhou Yellow River Highway Bridge. The fatigue load spectrum and the long-term prediction model of the traffic volume are also established in this paper. The Bi-Lognormal Distribution is used to describe the vehicle load probability distribution and the Monte Carlo simulations gives the results that the extreme value distribution of the vehicle load follows the Gumbel Distribution. The Logistic Model is used to predict the long-term traffic volume; especially the serving level and the capacity for traffic of highway are considered in the model. All the results can be as a part of the Integrated Life-Cycle Design or service decision of the highway bridge.
