College Bridge - 02.005
Design study of the bridge (including structural study) in collaboration with architectural practice SumProject.
The bridge is a suspension bridge. The project’s particularity lies in its complex plan geometry. The bridge describes an S in plan: this geometry resolves the accessibility to the bridge from both banks. The maximum slope of the deck is 5%. The bridge’s length is 203m with a central span of 86m. The deck’s width is 3.2m and consists of a steel hollow section of 1m high.
The spatial shape of the cable follows the catenary of forces that is determined by in-house developed software. The control of the vibration problems in such a project is one of the main issues. A calculation with forced response to harmonic loads has demonstrated that the user comfort level was sufficient without any dampers. Those results have been strengthen through measurement on the achieved bridge.
Nomination for the Competition Steel Construction 2010 in Category D: civil engineering. Highly commended for the Footbridge Awards 2011 'Aesthetics long-span' and 'Technical long-span'
