Analysis of Dynamic Reliability on Large-Span Bridge

For the current study of large-span bridges are mostly in the component level, the real structural system reliability analysis is still relatively small, so based on the theory of dynamic reliability analysis of structure, the overall bridge structure system for the calculation model is established ,then reliability analysis under the multi-dimensional seismic load and the effect of dynamic flutter are performed, the results of sensitivity analysis with different parameters are obtained, so it is useful basis for the bridge design and evaluation.
