What types of structures are addressed in Section 4.4?

Section 4.4 of the Ontario Building Code specifically addresses air-supported structures and parking structures. This section is designed to provide guidelines and regulations that are unique to these types of structures due to their distinct design and operational characteristics. Air-supported structures, which rely on internal air pressure for stability, have different considerations compared to traditional buildings, such as wind loads and ventilation needs. Similarly, parking structures have unique structural requirements related to vehicle load, circulation patterns, and safety concerns for both vehicles and pedestrians.

The focus on these specific types of structures in Section 4.4 is important as they present challenges that are not prevalent in other types of buildings. For example, ensuring adequate structural integrity and safety in air-supported structures requires different approaches compared to conventional frames or walls used in homes or industrial buildings. Thus, the precise regulations outlined in this section are essential for ensuring that these specialized structures are safe, functional, and compliant with the overall building code.
