The depth of the box beam will be 8”, 10”, or 12”, depending on the design requirements of a particular project. Check the Z15012 purlin from the attached BLUESCOPE steel design tables if the purlin was to be supported in double span between steel portal frames that are spaced 6. Too high a snow load means the purlins fail regardless of how close together you put them because a 2×4 or 2×6 flat can only span a certain distance between trusses as snow loads increase. Purlins design Purlins design. Corrugated roof sheets are available in a wide range of materials displaying various structural properties. Produced using G-90 galvanized steel, Z purlins can be lapped creating more structural strength to support continuous spans. You can also use the Wood Beam Calculator from the American Wood Council website to determine maximum rafter and joist lengths. All exposed timber was treated with 3 coats Rystix Timbercare.

The following load tables are prepared so the designer can readily determine the truss depth required to carry a uniformly distributed load over a given clear span. If you assume a 30 PSF ground snow load, then the max span is 6' 8", and the proposed 2x4 will not work, but a 2x6 will. Sub-purlins, which vary in size, weight and shape and are selected according to required span and loading, are spaced approximately 32 inches on center and are welded at right angles to the top cord of the open web bar joist. The tangential component of the roof load is considered to be acting on the top flange of purlins, here as the normal component and purlin dead load is assumed to act at its centroid. 3 Connection Details 13 3. It can be used with either cold-form purlins or open web joists, including our ClearBay option. Beach House. Notes to load capacities table 1. However, it is important to note that expected load is a crucial factor while determining this. Purlin systems with two or more spans can be lapped or unlapped.

The manufacturers of profiled metal sheeting and insulated panels provide load tables for their products, which may be used either to select a suitable profile or, where the profile has already been chosen, to determine the maximum permissible purlin spacing. thickness underlayment or 1 1/2” of approved cellular or lightweight concrete is placed over the subfloor, or. When the floor span exceeds 15m, it is generally more economical to change from a simple truss arrangement to one employing wide span lattice girders which support trusses at right angles. (If a steel purlin must span 24 feet between girders, it should be at least 12” deep. Contact our team on +44 (0)121 6016000. But that’s nearly impossible, as any structure will start to deflect the moment any load is placed on it. We manufacture any component from 1/2" steel subgirts to 12" section up to 10 gauge. Section properties and load span table brochure presents load span capacities for Albion Sections’ eaves beam, purlin and side rail systems. The nett load effect may act inward or outward (often the latter under typical Australian wind conditions) and the purlins may need to be analysed for both cases.
