What is the minimum uniformly distributed live load for a room intended for sleeping?

The minimum uniformly distributed live load for a room intended for sleeping is established by building codes, specifically the Virginia Uniform Statewide Building Code. Sleeping areas are classified as areas where occupants can be expected to sleep, requiring a higher consideration for safety and load-bearing capacity due to the potential for multiple occupants and the need for adequate structural design.

The correct value of 30 psf (pounds per square foot) reflects the typical standard established in building codes for this type of occupancy and ensures that the structural integrity of the building is not compromised under typical conditions. This value accounts for the potential weight of occupants as well as furniture and other items that may be present in a sleeping area.

In contrast, lower values such as 20 psf, 10 psf, and 40 psf are not applicable for sleeping areas, as they either underrepresent the minimum requirements for such spaces or exceed the necessary load considerations for different types of buildings or uses.
