Abstract Scope |
Heavy duty riveted steel grating is commonly used in bridge construction as it is relatively lightweight and is readily installed. One particular design concern is fatigue, which may affect overall durability and service life of the deck.In this study, the fatigue behavior of the deck focused on the riveted connection between the bearing, intermediate and reticuline bars. Fatigue tests have been conducted and were compared to more recent results from tests on both open-hole and riveted coupons. Lower bound S-N curves are derived for each condition and compared. A fracture mechanics model is used to examine fatigue cracking around a typical rivet hole. |
