Abstract EN
Deterioration of concrete bridge decks affects their durability, safety, and function.
It is therefore necessary to conduct structural rehabilitation of damaged concrete decks by strengthening them with fiber-reinforced polymer.
Of the recent studies on the strengthened structures, most have focused on static behavior; only a few studies have investigated fatigue behavior.
Accurate analysis of fatigue in concrete deck performance requires a more realistic simulated moving load.
This study developed a theoretical live-load model to reflect the effect of moving vehicle loads, based on a statistical approach to the measurement of real traffic loads over various time periods in Korea.
It assessed the fatigue life and strengthening effect of bridge decks strengthened with either carbon fiber sheets or grid carbon fiber polymer plastic using probabilistic and reliability analyses.
It used extrapolations and simulations to derive maximum load effects for time periods ranging from 1 day to 75 years.
Limited fatigue tests were conducted and probabilistic and reliability analyses were carried out on the strengthened concrete bridge deck specimens to predict the extended fatigue life.
Analysis results indicated that strengthened concrete decks provide sufficient resistance against increasing truck loads during the service life of a bridge.
