What is the maximum specified live load on a floor according to building regulations?

The maximum specified live load on a floor according to building regulations can vary depending on the type of occupancy and intended use of the space. In many building codes, including the National Building Code of Canada, a common live load requirement for general occupancy in areas such as offices is often around 2.4 kPa (kilopascals). This load is typically established to ensure safety, structural integrity, and functionality of floor systems under normal use.

When considering other options like 3.0 kPa, 1.5 kPa, or 4.0 kPa, they may apply to different types of spaces or uses. For example, assembly areas with fixed seats may require a higher live load, while residential spaces may have lower requirements. Hence, it's important to select the value that aligns with general occupancy guidelines, which in this case, is 2.4 kPa. This ensures that the building can safely accommodate the expected weight of occupants and furniture without risk of failure or undue structural strain.
