Research Group on Structural Engineering

École Polytechnique de Montréal, Montréal, Québec
Area(s) of Expertise

This is the largest and most versatile structural engineering laboratory in Canada. It consists of 2 testing slabs with an area of 630 m2 and a reaction wall with 2 wings 10 m high and 12 m long. The laboratory can do static, dynamic, seismic and impact testing. Loads can vary between 100 kN and 12,000 kN. Loading equipment can be set up to apply compression and tension forces from 1, 2 or 3 directions simultaneously. The laboratory has 9 independent monitoring stations, which means that several test programs can be carried out concurrently. Two of these systems have been designed for hybrid simulations, which involve laboratory tests carried out interactively with an analysis of the entire structure.

What the facility does

Experimentally studies of major civil engineering behaviours.

Earthquake engineers have to design buildings that resist structural damage during an earthquake. Even though the mission appears very difficult, even impossible, the engineers and researchers at Polytechnique Montréal are already testing a new structural concept that prevents buildings from collapsing and maintains their functionality. Report by journalists Claude D’Astous and Pierre Tonietto
