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...
Hi Team :)
I have been a member on this forum for a little while now and actively spend time reading posts - bit of a lurker.
I could do with some career advice pretty please.
I am an engineer and I live in Queensland, Australia. I am in my early 30's and I graduated from University with...
Hi all,
I am new around here. I am a grad engineer in Australia (QLD) and was wondering if anyone would have a reference guide they could provide me with that could give me an idea of slab on ground design for residential and industrial slabs. Looking to read and improve my knowledge bank...
Hi
I am working on a circular water tank that is 6m in diameter and the tank itself is 1m high. This tank is held 10m above ground on a frame. I am trying to work out the aerodynamic shape factor using AS1170.2 Cl C5.2.1. The formula for Cpb is only valid provided c/b is between 0.25 and 4.0...
Hi,
I am fairly new to structural design. In AS3600 2018 I notice that Clause 8.3.2.2 gives the maximum centre to centre spacing of reo bars as being lesser of 600mm and D. Am I correct in my understanding that this is the max centre to centre spacing between bars (across the width of a...
Hi
I use strand 7 at work. I have straus7 at home. I am trying to open a a work file at home on Straus7. It doesn’t let me and says it is not a straus7 file.
Can I open a strand file in straus? Is it possible? If so how?
Hi,
I am new to Strand7. This is what I would like to do:
I want to draw a hollow tube, 1m high with a radius of 3m and thickness of 6mm. Shape similar to a toilet roll carboard tube. I have created my cylindrical UCS. But I have no idea how to draw a circle that I can extrude up in to a...
