A Landmark: Multi-Span Steel Arch/Cable-Stayed Pedestrian Bridge
There is a growing awareness about the mental and physical well-being of people everywhere in Canada and for those living in relatively highly populated and polluted areas such as the Greater Toronto Area (GTA) in particular. The transportation projects continue providing venues for people to exercise and enjoy the stunning landscapes and natural sceneries all over the GTA. Herein, a high-profile arch/cable-stayed bridge over a flowing water stream is proposed to accommodate pedestrians and bikers while capturing the picturesque nature at a proposed park in the GTA. The bridge consists of a steel arch within the middle span that rises above the deck and is connected to the superstructure below with a series of cables. Toward the ends of the middle span, the arch extends gracefully below the deck to rest on the piers as end supports. The exterior spans are carried by steel girders and supported mainly by the substructure system (piers and abutments) while still connected to the arch for stability and controlling the arch buckling length. The utilization of corrosion-resistant materials and high-performance components, such as galvanized/sheathed cables and galvanized steel members, is considered. A sophisticated structural analysis is performed, using finite element modeling (FEM) to obtain precise figures of the straining actions and design demands, as well as representing the bridge construction stages. The most suitable design has been achieved while facing various challenges due to the complexity of the structural behavior during construction and thereafter. For comparison purposes, a simpler option of the concrete deck over variable depth steel girders is investigated. While the latter option presents favorable economic advantages, the arch/cable-stayed bridge is the recommended option as it offers the aesthetics level desired by the client and the public along with high sustainability and outstanding structural integrity.
