After this course

What you'll be able to do yourself.

Steel looks simple until the bolts won't fit during erection. This course teaches how to read sections, understand moment and shear connections, and make sense of light steel roof frames. Sizes and connections stay with the engineer. You learn to read them and make room on the drawings.

  1. 1Read section names and translate them into space on the drawing.
  2. 2Tell moment and shear connections apart from the detail.
  3. 3Read bolts, welds and stiffeners on connection drawings.
  4. 4Explain why light steel is strong and what must not be done to it.
  5. 5Coordinate with fabricators and the engineer when something changes.

Good for

  • Drafters who draw steel structures or roofs.
  • Junior architects who design sheds, canopies and long spans.
  • Inspectors who check steel frame erection.

Slide the value. The drawing follows, just like in the lessons.

A thicker plate makes the connection stiffer. The final size still comes from the structural engineer.

    Junior quantity surveyor

    As an architect I can now talk to the engineer without just nodding along.

  • Salsa Rahmadani

    Junior drafter

    Not many formulas, but enough to know why I can't just cut a hole through that beam.

  • Rizal Maulana

    Site supervisor

    The reinforcement chapter is very clear. I can now read rebar drawings on site.

What can I try for free?

All of chapter 1, "Steel sections": 6 lessons, about 38 min. No card needed. If it isn't for you, stop there.

04

Do I get a certificate?

Certificates come from track exams, not single courses. This course counts toward Structures for Architects. The exam runs 60 minutes and you pass at 75 percent.

05

Can I use these drawings on a project?

No. Every drawing in the course is an illustration for learning, not for construction. Use them to understand the logic, then follow your firm's standard and your engineer's drawings.
