Steel Detailing Tips – Modelling Stud Walls

What is the purpose of this lesson?

The purpose of this lesson is for you to:

  • understand what a stud wall is, and
  • understand the importance of putting holes in the beams in order to allow for the erection of stud walls.

 What is a stud wall?

A stud wall is made up of:

  • A frame (in our situation this frame will be a steel frame) and
  • timber members which go in between the steel frame and
  • a covering of 13 mm plaster board to cover the frame. The plaster board covering is not shown in the diagram below.

In steel stud walls, light steel pressed members or standard steel studs (mostly standard steel studs) are used instead of timber.

Please view the diagram below.

Shows what stud and nogging members are.

What is nogging?

Do you see the horizontal 90 x 45 timber pieces – the short red horizontal timber members? These short timber members are called nogging.

The nogging members of a stud wall are usually smaller in size than the main vertical members.

Nogging members run horizontal and give some strength to the wall.

Inside of the wall is empty space. Insulation material can be put in there.

Cross pieces are called NOGGING.

The Key Point of this lesson:

  • It is important that you provide dia 14 holes on the steel beams and columns so that the timber pieces can be bolted to the steel pieces. Imagine you have some steel beams/columns and also some timber. How will the timber columns be attached to the steel columns so that the structure doesn’t move? Holes need to be drilled so that the timber pieces can be bolted to the steel beams. You need to provide holes in the steel so that the timber members can be bolted to the steel.
  • You need to rotate and orientate the beams so that its face runs with the stud wall face.

A stud wall cannot stand in the wall without some connection.

Please see the below diagram to show you how things are drawn in the engineering and architectural drawings:

Now see below how you will need to detail the above design:

Tek1 Courses – AS 1657 & AS 1428 Training – Now Available to Public

Experts in AS in Stairs/Handrails/Ladders

We’ve done a lot of work on Australian Standards – both public and private access. We specialise in Steel Detailing – and have a special focus on stairs and ladders. Since we deal extensively in this area, we require all our staff to be thoroughly versed in the Standards. Consequently, we have developed testing frameworks to ensure that all staff are well trained and accountable.

Our Testing Infrastructure Now Freely Released to the General Public

We are now releasing our testing framework to the public at no charge. Now you – yes you – can access our internal testing framework to help learn and reinforce your knowledge of Australian Standards – namely, AS 1657 and AS 1428.

We hope and trust you will find it of immense benefit.

Keep people safe – design and build according to the safety standards prescribed by law.

Where are the courses?

  1. Follow the link: http://tek1engineeringservices.com/onlinetests/course/index.php?categoryid=5
  2. Click on the relevant course
  3. It is best to create your own account – I know it’s a pain but it’s the best way. If you really don’t want to you can log in with a common account available to the public, but there are serious limitations with that approach. If you want to do the latter, here are the credentials – but I strongly urge you to create your own account: 
    • username: student

AutoCAD-Tekla Interoperability

Tekla – AutoCAD Interoperability Tool

Tekla licenses are pricey. About $30k + maintenance per license. What if I told you that you needed 30-50% less licenses than you currently hold. That’s a huge cost saving, isn’t it?

If you only need 5 licenses (as opposed to 10), then you’ve saved $150k instantly, plus maintenance.

AutoCAD licenses are significantly cheaper.

But if only the work you did in AutoCAD could be transferred into Tekla? That would save you some licenses. That’s just what I’ve done here in my latest project. Now a significant portion of any modelling job can be done in AutoCAD and simply imported into Tekla.

You can check it out here:

Human Resources Problem

Interoperability will also help improve the quality of your work: it’s tough finding people who are highly skilled in Tekla. What if I told you that you could use an AutoCAD draftsperson instead of someone well versed in Tekla, to do the same job? Now you have a potentially infinite pool of candidates to draw from.

AS 1428 – Section 11 – Nosing and Tread Requirements for Stair Construction (Public Access)

We continue to release our in-house precis on Stair way construction. Reading the standards is terribly tedious so we have developed a way to easily cross check the requirements and to make sure that stairs are built according to standards.

Unfortunately it’s too common for us to see designers produce drawings which simply do not comply to the required standards. So it is of the utmost importance that fabricators are able to: (i) know and understand the standards and to independently verify that their drawings do comply. Only a fool would 100% trust in an architect to draw to standards – we’ve seen it way too often. You, the fabricator have to check everything yourself. Here are some of the in-house memos that we use to ensure that our stairs always comply:

We wish to share it with the world – and we hope it helps you immensely:

Stair Outline Routine – AutoCAD Plugin – Code Attached

An example of the type of stairs we draw. We do a lot of stairs. Both AS 1428 and AS 1657 compliant stairs.

We continue delving into our discussion of stairs. The boss hates it when I do things like this – releasing code to the public. But it’s too good not to share. Below is a routine you might find useful. We use it to model stairs – it’s super fast, and efficient. It allows us to try different things out and to discard what doesn’t work with ease. I’ve gone to the effort of drawing up an entire flight of stairs and then realised that I’m missing a tread. Then I’d have to redo the whole thing from the beginning. Once you have this outline done, the a good chunk of the work is finished.

One of our many, many versatile routines:

Here is a gif of the project:

And here is the code for the benefit of study.

I suppose I should refactor it, but I don’t think I’ll be changing it any time soon. So why worry?

AS 1428 Stairs-Handrails – Tek1 Compliance Checklist

We do a lot of work on handrails – both public access (AS 1428) and also private access (AS 1657).

Anybody can draw a staircase – and if you’ve ever fallen down some stairs, or if you’ve ever walked up some stairs which do not comply to any standards – then you’ll immediately realise the importance of having stairs that actually comply. It’s paramount for safety.

Designs of non-complying staircases is something that we see all too often. All the time. The costs of fabricating non-compliant staircases is monumental. We’ve invested a lot in training staff to ensure they follow the standards. And for the benefit of the industry, here is a cliff notes version that our guys use to remind them of the requirements needed for public access stair handrails.

It is a first class precise that allows detailers to quickly check compliance without wading through reams and reams of legislative like prose within the AS 1428. This precise will be the norm in the industry and is worth its gold. It was made right here by Tek1.

Steel Detailing Tips: How to markup A Tekla BIMSight Model

Please watch this video on how to markup the Tekla BIMSight Model. It describes the 4 essential steps required to effectively markup a s bim sight model

Most important is make your comment public, else when you send the BIMSight model, no one will be able to see your comments. Users can mark up the same model and return to you with their own comments.

 

Watch the video below on how to send your marked up BIMSight Model to your clients.

Designing Bent Members

Designing Bent Members

Consider the below member: notice how it has two bends in it.

When designing such a member the detailer needs to be aware of how these members are made.

Check out this video for a beautiful explanation:

That is just how handrails are produced. The steel members are bent around a radius set on a machine. If the design is too complex, then detailers need to be aware that fabricators may resort to welding two pieces of metal together to make it work.

 

How to Copy Tekla Component Settings Between Two Models

In this article I am showing how to take your Tekla component settings from one model to another.

There are more than one way to do this. But this could be the easiest.

Other ways are setup your computer to read the favorite componets from a location, Set up the network such that all Tekla machines load favorites from a location.
