Structural Reliability Analysis of a Steel Truss Bridge Based on Monitoring Data

摘要：

The stress histories of monitored members are used to get stress spectrums for a steel truss bridge through rain-flow algorithm, then the distribution functions and their characteristic parameters of stress spectrums are obtained to simulate the stress spectrums numerically through Monte Carlo methold, which used to evaluate the structural fatiguelife based on stress-probabilistic model and accumulated damage theory, and the fatiguelife and its hot spots of whole bridge are acquired, which is important for the strategy of bridge management.
