Almost all structures will deflect during service.
Ceiling designers should be aware of the expected deflections of the building structures as they affect the ceiling.
These deflections may be due to both dead and live loadings.
In fire rated ceiling framing, thermal expansion of steel frames should be expected during fire service.
Designer should make due allowances for these effects.
The ceiling designer should properly consider framing design and layout around openings in ceiling systems.
Ceiling spans are determined by various design criteria including: weight of ceiling, wind loading, deflection limits, material size and required spacing's.
For span information to satisfy specific design criteria contact Peer Design.
Some examples detailing various component scenarios have been provided to assist in the choice of the correct product for most building projects.
