Hi Structural Team
A student was asking me to explain the difference between pinned and fixed connection by concrete beams.
As I started to explain, I realized that this is actually not easy to explain or define the difference, because we actually never have such cases where the beam...
@littleinch: thanks for support, you make feel better ;-)
I like your statement " "why was he not supposed to build the brick walls on propped structure" is that the prop was a temporary construction feature" this covers me a bit
I attached a photo of the site
@dhanger: you right could have been done this way but not needed.
I just regrade that I did not have a note on my drawings which clearly stipulates that this is not allowed to built walls on a propped structure :-(
Hi guys
in our office we have a debate about the best welding of the angle section on a gusset plate.
See attached image. I have my own theory and my colleagues also they own one. Now I wanted to extend the debate on this forum to get maybe some new ideas.
Where and how would you weld the...
@Jayrod: convinced ;-) thank you guys for opening up some new perspectives for me. Ok so C is out but then B shoudl be the optimum setting out when your inner sections are smaller to line up the center of gravity lines, or?
when you detail a truss, would you give all the dimensions of all the vertical and diagonal members as well?
dimensions of gusset plates? or is it going to much into detail?
@gravityandinertia: you very right but then why not version c? there you also have the increased welding area but you recuse the gusset plate.
Do designers actually look into best lining up of center of gravity lines?
see image below
ok, so the one question is sorted but now I get another question.
Why am I seeing always the gusset plates outside of the member? Why don't we weld it inside? The center of gravity lines would then even line up much better
see attached image is version B and C not the best solution? and most...
that you guys, you all say the same basically, you all are also experts in this field but now an weak contractor wants to argue and I would like to show it to him somewhere written down. I need something to relate to.
Hi, I have some problem because the contractor was building brick walls on propped structure.
Now what happens after they "de-propped" the slabs, the bricks started to crack here and there.
How can I prove to the contractor that this was wrong? Obviously he is now arguing that why was he not...
@Klaus: hhmmm....ok you might have a point. So this is purely a practical reason for the cuts to be straight? No structural reason for it? Would you detail each gusset plate? This would be an overkill,or?
Reagrds
lolobau
@ Klaus: this could be a reason but does it really make a big difference if you cut straight or skew? You need to cut anyway and you would save on the gusset plate size.
Hi
I was wondering why do we always cut the angle sections by truss connections straight?
When we would cut it parallel to the main bottom and top members then we could reduce the gusset plate size by a significant amount.
This would also lead to shorter "gaps" between the members fixing points...
Hi guys
thanks you so so much for the very informative feedback. It makes totally sensse what you all write
but since the vertical reabrs receive so much compression then the links (stirrups) become then also very important to keep the vertiacl steel in place.
Some engineers say that this...
