Objective | OP2 Structural Sufficiency of the Building |

Application | Application 1: Specified load due to the accumulation of rainwater
on a roof or other building surface whose position,
shape and deflection under rain load make such an accumulation possible, where
scuppers are provided.

Intent | Intent 1: To limit the probability that the rain load used for the
design of structural elements supporting roofs where scuppers are provided
and on which rain can accumulate will not take into account the maximum expected
accumulation of rainwater on a catchment area of roof, including an allowance
for rain accumulation above the scupper level, which could lead to the excessive
deformation of, or excessive stress in, structural elements, which could lead
to damage to the building. Intent 2: To limit the probability that the one-day rainfall value
used will not be compatible with the geographic characteristics by directing
Code users to Sentence 1.1.3.1.(1) [Appendix C],
which could otherwise lead to the excessive deformation of, or excessive stress
in, structural elements, which could lead to damage to the building.
