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?
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.
But it’s not infrequent that we see stair designs which do not comply. Who draws them up? Architects! There are architects out there who don’t know what they’re doing – let me tell you – and they’re extremely costly to the industry and a safety hazard. We’re the last line of defence. If a staircase is fabricator that does not comply – it’s not the architect who feels the financial pain: it’s the fabricator, the builder and the shop drawer. So it’s critical that you get the design right.
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 sample that our guys use to remind them of the basic requirements needed for public access stair handrails.
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.
To open a tekla structure model multiple options are available as:
1. File> Open
2. Keyboard user input Ctrl+O. (Default tekla command)
3.Using the open icon shown as a folder image
Either of the methods can be used to open a tekla structure model , but before moving to the open dialogue display the existing model has to be “save’ or ‘don’t save’ dialogue will be displayed to confirm the existing model actions (Since only one model can be worked on in tekla). Once the selection is made we can move to the open model dialogue to proceed to the next model.
