Application
Application 1: 
Specified uniformly distributed live loads due to use and occupancy, and their application for the design of structural elements of buildings, where the use of an area of floor or roof is included in Table 4.1.5.3.
This applies to buildings described in Sentence 1.3.3.2.(1) of Division A and to buildings to which Part 9 applies [see Sentence 1.3.3.3.(1) of Division A for application of Part 9] that are required to be designed in accordance with the requirements of Part 4.

Intent
Intent 1: 
To limit the probability that:
  • the live load due to use and occupancy will not take into account the expected accumulation and distribution of people and objects on the floor or roof surface, including an allowance for dynamic effects due to people, and
  • the live load due to use and occupancy will be less than the prescribed minimum value.
This is to limit the probability of structural failure, which could lead to harm to persons.
