Abstract

One of the major causes of road infrastructure failure is traffic-induced fatigue of bridge superstructures, in particular concrete bridge deck panels Deterioration of steel reinforced concrete (RC) bridge decks a result of aging and fatigue is on the rise in many developed countries including Japan. This paper presents experimental work done in investigating traffic-induced fatigue mechanism of a normal RC bridge deck and the strengthening by fiber-reinforced polymer (FRP) sheets to extend fatigue life. Discussion is focused on experimental observations and development of a stress-passage (S-N) relationship that provides estimation to the fatigue life of deck as a result of FRP strengthening. Within the scope of study, the strengthening by FRP has proven to be a viable and relatively simple solution in salvaging RC bridge decks suffering from moderate level of fatigue damage, with fatigue life up to 28 times longer than that without strengthening.
