3.1.4.6.(9)ATTRIBUTION:
Most technical provisions of the BC Fire Code describe how the code’s objectives and functional statements are achieved. However, some provisions, like this one, do not relate directly to a code objective. The following analysis is provided to assist in understanding of the provision.
APPLICATION:
Beams and girders in heavy timber construction in buildings described in Sentence
1.3.3.2.(1) of Division A where:
- this type of construction is specifically mentioned in this Part, or
- combustible construction is permitted and is not required to have a fire-resistance rating more than 45 min, as stated in Sentence 3.1.4.5.(1).
This also applies to buildings to which Part 9 applies [see Sentence
1.3.3.3.(1) of Division A for application
of Part 9] where heavy timber construction is considered to have a 45 min fire-resistance rating, as stated in Sentence
9.10.6.2.(1).
INTENT:
To describe the method of connection for beams and girders
entering masonry to limit the probability of premature structural failure
of the heavy timber construction during a fire.
