Why it matters to clients
Bridge theory, tested on real structures.
The research above examined how stay spacing, stiffness, deck material and anchorage systems change the static, dynamic and seismic response of cable-stayed bridges, work that later informed the design and construction of long-span airport roofs, tower arches and marine structures the founder went on to deliver. The 2015 paper on rooftop green infrastructure grew directly out of the rooftop solar portfolio he led in Ontario.
Cable-stayed bridges
Ten papers on one structural type
Parametric, dynamic and seismic studies published from 1996 to 2003, including two in the ASCE Journal of Bridge Engineering.
