Hi
It would be nice to hear some thoughts.
We are a fairly small company doing pretty well we have been in the business quite a while and getting a lot of work with out needing to market.
At the moment our target is upmarket residential some commercial and so on but nothing big.
I want to...
Hi guys
I have been struggling with the correct procedure to calculate if a masonry wall is able to withstand a bolted steel frame cantilevering from the side of it. We have done a lot of masonry wall panel design cracked sections uncracted panals etc. But not sure about this one. Cause I can...
Hi All
I just need some advice I need to design a cold formed lip channel front to front, but because of the section seen as a custom section in my design program (Prokon). I can not check the section in the strength checks. I will have to do it by hand but don't have the time.
So can I check...
Hi All
I need to manually enter a stress vs strain curve for steel material G550 apparently it is mostly used for cold formed sections. Because of its min BMT (base metal thickness) of 0.42mm it does not comply with South African standard of min 0.5mm. It is under amendments. However as things...
Hi Guys
I need some advice. If you cast a strip foundation say 750mm X 300mm deep and you have your nominal steel in and a pipe like a water pipe needs to run through it. On top of the foundation a foundation wall is built 110 brick 100 filled cavity and 110 brick to plinth level.
Now do you...
Hi Guys
I have a question and seems I get a lot of uncertain answers from other engineers not on this forum.
So if I could ask please try not to be vague.
If you design a beam member as pinned supported at both the ends and you use a fixed connection and not just a normal pinned would that...
Hi Guys
I did a wind loading model on a Duo-pitch canopy 6m wide X 50m long, pitch is 2 degrees and I loaded the canopy as per our design code in South Africa. Which is up lift, down force, then up and down force on only the one half of the roof or one side of the ridge.
So what about "draft"...
Hi, Guys
I just want to confirm something. If a Base has a moment on it from a steel post and the post is imbedded into the concrete that would make it fixed, now is it a must to have steel (re-bar) in the concrete base because of the moment or is it right to make the base a certain depth for...
Hey Guys
I need to design or check a connection of a steel post 100 X 100 X 2MM square tube that is cast in the concrete footing.
The post at the bottom has 2 steel re-bar drilled through the post and horizontally imbedded into the concrete. There is a big uplift force of around 30 KN.
So the...
When a code says Construction joints to be kept to a min how many would that be. How would one specify a good (strength integrity) construction joint in a beam e.g. Vertical joint, Horizontal joint, in middle of beam, rouged texture, concrete mix ratio ex.
