What is the tell tale sign that tells you it is a fully fixed - or close enough? Is it the stiffener plates? I am trying to train my eyes to distinguish between connection types.
Thanks for your response
Hey everyone,
I’m currently brushing up on structural engineering concepts, especially around connections, and I thought I’d share something I’ve been analysing to get better at spotting connection types in real-world structures.
The attached photo is of an overhead sign structure that I see...
You solved it! Yeah I was releasing both beams on either side of B. I restrained one side and released the opposite side and it solved the issue. I got the same BMD and SFD as my hand calc.
Now I understand why we can't release both sides - because the node will be free to rotate and the whole...
If I remove the rotational release on either side of node 2 then the solution works. However to mimic the pin connection at node 2 I released the rotation around the z-axis. When I run it, the solver says the following:
"Global stiffness matrix singular at equation 26 - Pivot = 0.000000E+00...
Hi Team,
I have just been brushing up on my structural analysis. I picked an example problem from a text book to draw a BMD and SFD.
This is the problem I picked:
I undertook a hand calculation as follows:
I am confident the solution is correct but thought of double checking it in a...
Hi Team,
An elementary question coming from a green engineer...
I have read on the forum multiple times where people have said it is conservative to assume that the connection is pinned as opposed to assuming it to be a moment connection.
In university they taught us the difference between...
I cannot thank you all for your encouraging words of wisdom. It has really encouraged me to look in to this further with great enthusiasm. I will actively work to make this happen for me. Thank you very much again for your kind words.
In Queensland we have what is called RPEQ, which stands for Registered Professional Engineer Queensland. Registration as a RPEQ is formal recognition of the qualification and competency of an engineer in the State of Queensland. Like other professions such as builders and architects, engineers...
You are not wrong about the pay cut. It's something that I will have to accept. I have experienced this in the past when I left construction to join a private consultancy - I took a large pay cut. I was happy to do so with the intention of furthering my knowledge and skill set in engineering...
