Steel Design 2 (single-storey buildings)

One portal frame building from layout to the last joint: load paths and bracing, cold-formed purlins and girts, cold-formed sections, rafters and columns as beam-columns, the eaves haunch, the apex and the base. It builds on Steel Design 1 and uses the STATIX steel calculators.

Lessons

Lesson 1The portal frame buildingLayout, frames, purlins, girts and bracing, the gravity and wind load paths, restraint and the combinations for a light roof. Lesson 2Purlins and girtsLipped channels and zeds, spans and laps, bridging, gravity and uplift, buckling checks, deflection and girts. Lesson 3Cold-formed sectionsLocal, distortional and global buckling, the Direct Strength Method, struts, built-up pairs, beams, web crippling and screws. Lesson 4Rafters and columns as beam-columnsPortal actions, in-plane and out-of-plane lengths, purlins, girts and fly braces, sway and serviceability. Lesson 5The eaves haunch connectionWhy a haunch, bolt rows and T-stubs, the compression zone, panel shear, stiffeners, welds and reversal under uplift. Lesson 6The apex connection and the baseThe apex under gravity and uplift, the pinned base, holding-down bolts and shear transfer.

Who it is for

Students and graduate engineers who have done a first steel course.
Technologists who design or check light industrial buildings.
Engineers new to portal frames and cold-formed steel.

Before this course

It builds on Steel Design 1 (members, bolts, welds and base plates) and uses the wind loads of Loads 1. It does not repeat them.

The STATIX tools it uses

The wind load calculator and the quick tools.
The cold-formed purlin and cold-formed member calculators (SANS 10162-2, Direct Strength Method).
The steel member calculator (SANS 10162-1 or EN 1993-1-1).
The eaves haunch and apex haunch calculators (EN 1993-1-8) and the base plate calculator.

How each lesson works

Learning outcomes and what you need before you start.
Short theory with many sketches, with clause numbers to look up in your own copy of the code.
Worked examples by hand, every number shown, checked against the STATIX calculators.
The same problem in a STATIX calculator.
Exercises with answers, a short self-check quiz and the lesson on one page.

Universities and colleges
