Concordia University's Engineering, Computer Science and Visual Arts
The new Engineering, Computer Science building and the Visual Arts building complex is located in the heart of downtown Montreal. The twin towers bring art and engineering together. The two concrete framed structures are 17-storeys and 12-storeys with two basement levels. Total covered area is over 700,000 square feet. The vertical campus is built in increments of three storeys, each with a glass walled atrium that features a spiral staircase.
The lateral resistance to earthquakes is provided by a hybrid system composed of concrete shearwall in the central core and steel bracing with Pall Friction Dampers in staircases located at the ends. The use of friction dampers significantly reduced the storey drifts and torsion and the goals of performance-based design were economically achieved. Construction was completed in 2005.
