ABSTRACT
The search for innovation in civil engineering has led to the creation of the Winnipeg Principles for the design of bridge decks using an arching action. The structural health monitoring of the steel-free bridge deck was conducted by installing sensors. System health monitoring indicates that the load sharing of the Salmon River Highway Bridge is similar to conventional decks. The first-generation steel-free deck slab in Canada was cast on the Salmon River Bridge, part of the Trans-Canada 104 Highway in Nova Scotia. The second-generation steel-free deck slab exhibits the same behavior as the first-generation steel-free deck slab, with the exception of a longitudinal crack at the mid-point between the girders. This chapter describes the fatigue behavior of cast-in-place second-generation steel-free bridge decks. Although cast monolithically, the bridge deck was divided into A, B, and C segments. ISIS Canada intends to significantly change the design and construction of civil engineering structures.
