Technical Notes.
From The Work.
Short Practice Notes Used On Industrial Jobs. They Are Guidance, Not A Standard, And Not A Substitute For Project-specific Engineering.
Revision Log
Website and tools changes are recorded on IQ-DOC-001. One line per revision. Tool calculations stay Rev 0 (indicative).
Site Investigation
Start with what can be seen, measured and photographed. Record the load path, interfaces, access and what the drawings get wrong. An information-gap register is more useful than a guessed as-built.
Mill Table Vs Geometry
IQEG catalogue properties omit root fillets. Use mill tables (OneSteel / Liberty / ASI) for certified section properties. The drawings show d, bf, tf, tw and r so the geometry can be checked.
Fillet Welds SP / GP
AS/NZS 1554.1 category and throat govern capacity. Minimum and maximum fillet size follow the thinner part and the procedure. The weld-group tool is a line-group solver, not a connection catalogue.
AS 1657 On The Desk
Walkway ≤ 7°, ramp 7–20°, stair 20–45°, ladder 70–90°. Top rail 900–1100 mm, openings ≤ 450 mm, toe board 100 mm. The quick-reference tables are indicative — the current Standard and the occupancy in AS/NZS 1170.1 govern.
Bolt Groups
The elastic point method shares N, Vx, Vy, Mxx, Myy and Mz onto bolts as points. Compression is counted in the N distribution; the tension check uses max(N, 0). End plates with a contact block, prying and T-stub behaviour need a different model. IQ-CAL-013 is a group solver, not a connection catalogue.
Indicative Tools
Every calculator on this site is Rev 0 and indicative. Check mill tables, weld procedures, bolt assembly certificates and manufacturer data before use. IQEG will prepare a project-specific package on engagement.
We will confirm the scope before work starts.
