Dynamic Reliability Assessment of Heavy Vehicle Crossing a Prototype Bridge Deck by Using Simulation Technology and Health Monitoring Data

Overloads of vehicle may cause damage to bridge structures, and how assess the safety influence heavy vehicles crossing prototype is one challenges. In this report, using a large amount monitored data collected from structural health monitoring system (SHMS) in service bridge, which type large-span continuous rigid frame adopting FEM simulation technique, we suggested dynamic reliability assessment method report impact on during operation. first place, by strain data, selected time range before opening traffic, quasi around embedded sensor with no traffic load effects obtained; then, technology, model main span built ANSYS software then when corresponding middle-span web plate comprehensively analyzed discussed. At last, assuming that beam stress state change stage approximately linear elasticity under loads impact, authors got level bridge. Based number field measured value calculated our proposed methodology more accurate. The paper can do good for not only management but also analysis bridges.
