Based on the bridge health monitoring data, the traffic-load effect model for arch bridge suspender was set up using
direct statistical method. Firstly, the Bridge Health Monitoring System (BSHM) set up on the Ebian Dadu River Bridge
in Sichuan province to obtain daily traffic-load effect of suspenders was introduced. Secondly, the section distribution of
suspender traffic-load effect was researched by statistical approach using monitoring data. Finally, the probability
distribution of maximum traffic-load effect during design period was given. The statistical result shows that the section
distribution of suspender traffic-load effect follows lognormal distribution and the probability distribution of maximum
traffic-load effect during design period follows generalized extreme-value distribution. The traffic-load effect model of
suspender was different with the design code given which may underestimates the real load effect level. It's the first time
in China to determine the traffic-load effect probability model for arch bridge suspenders based on actual acquired
monitoring data using statistical and probabilistic approach.
The determination of traffic-load effects, which guarantee the safety evaluation results credibility, is an important step
for safety evaluation of arch bridge suspenders. Focusing on the traffic-load effects calculation for arch bridge
suspenders, firstly, the special feature of traffic-load effects, "sit-specific" "component -specific', was talked about, and
the importance of traffic-load effects measured value was pointed out too; secondly, the component of suspenders' load
effect monitoring system with fiber sensor was introduced in detail; finally, the theory and process of the maximum
value of suspender's traffic-load effects during the rest service period using in-service data was researched. Using this
maximum value in safety evaluation, the evaluation result is closer to the real situation.
