Swan River Pedestrian Bridge in Perth - Structural Design Story from the Concept to the Construction

This paper resume the story of the design of the new “Swan River Pedestrian Bridge” now under construction in Perth, Australia. The bridge is formed by three steel decks connected with cable hangers to three steel arches, the central span is 144[m] and the two lateral 84[m]. The geometry of the steel arches follow the free form shape designed by DCM Architects, in order to achieve an iconic image as required in the tender of 2014.

Studio Majowiecki has been involved as structural designer from the tender phase to the executive design in the team of York Rizzani Joint Venture. During the concept phase of the tender proposal many static and architectural schemes have been analyzed in order to find the solution that combine in the best way the requirements in terms of aesthetic image and structural efficiency.

Due to the complex geometry of the bridge it has been necessary to adopt particular solutions for the design and analysis of the arches and deck structures, such as the joints between the steel elements of the lattice structures, the connections between the membrane cladding and the chords and some details that allow the completion of assembly procedures.
