References

Final member selection, loading, connection design, fire design, fabrication and compliance must be verified for your specific project by a suitably qualified structural engineer. Standards are revised; check the edition in force where the work is built.

Verification

StructuralSteel.ai provides technical reference information and links to authoritative sources. Project specifications, applicable legislation, current standards editions and requirements of the responsible engineer or authority should always be verified before fabrication or supply.
