Stade de soccer de Montreal is a community soccer facility that hosts indoor and outdoor fields. The hybrid steel and timber structure consists of large spanning members for an unique experience. The 135,000 square foot building was designed by HCMA Architects + Design who worked alongside Nordic structures to create custom 69 by 4 meters built-up box beam principal long span members. The architectural cladding contour lines of the building were inspired by the nearby landfill research establishment.
The principal long span roof members consist of built-up box beams made from glue-laminated timber (Glulam) and cross laminated timber (CLT). The use of mass timber offers a multitude of benefits in regards to the performance and sustainability for the environment. Nordic’s mass timber products are manufactured from sustainably-managed forests with readily available materials. Furthermore, wood’s capability to provide long-term storage of absorbed carbon byproducts results in substantially fewer greenhouse gas emissions compared to many non-wood materials.
Wood’s versatility as a material also allows it to be disassembled and reassembled either in new buildings broken down into wood fiber products, or utilized as biochar.
In Montreal, climate conditions are harsh during the winter months. Heavy snowfall results in a roof designed to support local snow loads of 2.8kPa. The structure incorporates purlins running perpendicular to the primary load-bearing built-up beams. These glulam purlins transfer their loads to the 4 meter depth box beams, where the load is distributed to the steel w-flange columns on either side of the building down to the foundation. Intermediate support and resistance to lateral load is provided by steel cross-bracing that runs between the w-flange columns. The large span built-up box beams act as a truss system, where the top and bottom glulam flanges are designed to act in compression and tension, respectively, and the CLT web is reinforced by glulam stiffeners that act in compression. This solution, although complex, allows for snow loads to easily migrate through the structure.
