STRUCTURAL FRAME
Sustainable Construction -
The elements of structure – structural frame, loadbearing walls, fl oors,
external walls, separating walls, compartment walls and protecting
structure must have a minimum period of fi re resistance rating.
Concrete and masonry construction are readily accepted when they
are constructed according to “deemed to satisfy” provisions with
appropriate covers.
For steel frame structures, they can be designed in composite construction
to exploit the inherent fi re resistance of the steel structures
(please refer to page 61 for a quick guide). The overall stability of the
steel or composite frame will have to be checked at the fire limit
state if a fire-resistant design is adopted. In cases when designing
in composite is not possible, protection such as fire-rated boards,
cementitious spray-fi reproofi ng or intumescent paint can be used to
achieve the required fire resistance. Section 3 will provide more
details of the various types of fi re protection.
