Structural Material Standards: Steel, Aluminum, and Glass
Steel Building Systems and CSA A660
According to Section 4.3.4.3, all steel building systems must be manufactured by companies certified in accordance with CSA A660. This certification ensures that the manufacturer maintains a high standard of quality control and engineering, which is a non-negotiable requirement for industrial and commercial projects.
Aluminum Design Basis
Per Section 4.3.5.1, structural members made of aluminum must conform to CSA S157/S157.1. These structures must utilize limit states design in accordance with Subsection 4.1.3, ensuring they can withstand stipulated loads while maintaining material efficiency.
Structural Glass Requirements
Glass used in buildings (Section 4.3.6.1) must be designed using either CAN/CGSB-12.20-M (with a 0.75 wind load adjustment) or ASTM E1300 (with a 1.0 wind load adjustment). This is critical for modern architectural designs that feature large glazing areas common in high-end Muskoka cottages and London commercial fronts.
Design Requirements for Special Structures
Membrane and Parking Structures
Section 4.4.1 requires membrane structures to conform to CSA S367. For parking garages, Section 4.4.2 mandates compliance with CSA S413, focusing on durability and performance for storage and repair facilities subject to heavy vehicle traffic and environmental exposure.
Industrial Storage Racks
In warehouse and retail environments, storage racks and their anchorage must be designed for specific loads in accordance with Section 4.4.3.1. Proper anchorage is vital for safety and compliance in any logistics-heavy project in Southwestern Ontario.
