2. Results are only for the stress distribution case as shown Combining stress cases as per AS4600.

3. Users should derive the section strengths for each case by fi rst determining the fl exural torsional strength of the full section and apply direct strength formulae to account for the local and distortional buckling limits.

SAFE ROOF PURLIN SPANS

The safe spans below are suitable for sheds and class 1 structures with the following assumptions:

Non-cyclonic sites only Cpe = -0.9 and Cpi = +0.2 High Pressure Zones KL = 1.5 and 2.0 included Max roof span allowed - 12m All Spans to have 1 row of bridging. 15% Lap must be fi tted to all mid supports Cleated or bracketed fi xing Only - No Flange Bolting. Results are for at least two spans. Full calculation of requirements using Steeline section properties should be carried out for full verifi cation.

This table is to be used as a guide only. This information presented is for estimating purposes and is the responsibility of the client to ensure they get their structure independently engineered. Steeline Roofi n Spot accepts no responsibility for structural integrity or workmanship.
