Intent
Intent 1: 
To limit the probability that the live load for an area of floor or roof intended for two or more occupancies at different times, which is used for the structural design, will not take into account the maximum expected accumulation of weight due to people and objects for all of the intended occupancies, which could lead to structural failure, which could lead to harm to persons.
