A major innovation is happening in the structures laboratory at the Department of Civil Engineering at Queen’s University. The first ever Rolling Load Simulator – R●LS in Canada for testing highway bridges is making a big impact in the lab. This machine is capable of delivering tens of years’ worth of heavy truck loading, simulating the long service life of a highway bridge at full scale. Bridges are the ultimate expression of art and science in structural engineering. Results from further tests in this machine will advance our understanding of the complex behavior of bridges under realistic loading conditions.
