4.1.5.8.(1)

Intent 1:

To limit the probability that the uniformly distributed live load for churches, courtrooms, lecture halls and theatres with fixed seats, for classrooms, where people are typically distributed uniformly over the floor area, and for roof areas that are designed for the minimum 1.0 kPa loading stated in Table 4.1.5.3., will be reduced where there is an increase in the tributary area of floor or roof, which could lead to:

• the excessive deformation of, or excessive stress in, structural elements, which could lead to damage to the building, or
• the excessive deflection or excessive vibration of structural elements, which could impede the intended use and occupancy of the building.
