A deliberately provocative title to get a conversation going. :) And I fully expect to be proven wrong by some nimble engineers who are more skilled and comfortable in this area that I am.
The instigation this thread is I've just returned from a site visit from a owner who is removing a load...
I hope the title caught you attention, and I hope you are enthused to have your thinking caps on.
So we as good engineers know that, we should use thick/(or gusseted) plates when we are designing connections with significant tension loads. A big part of this is so we can use a rigid plate...
Australian Engineer Registration Discussion (NER vs RPENG, Member vs Non-member)
Hi All,
The thread subject probably is self explanatory of the question I have and the topic of the thread. I am keen on feedback on peoples choices and experiences. The benefits and the costs of different...
Hi all, Second time this week I've reached out on what is a pretty basic question but it is something outside my normal experience. As I said in the last post feel free to flame away on me, an engineer who is poking his head outside his normal area of competency.
Background: A client...
Okay. I don't won't to be one of those posters asking extremely basic questions. Buuuuuut, I will do so and suffer any flaming I deserve. [smile] [machinegun][cry]
I have a upcoming job with small liquid tanks (8m high, 3m dia). It isn't something I've ever done before but I'm sure I can...
Does anybody have some good references on understanding and dealing with fatigue failure in steel? As I understand it is exacerbated by cyclical stress (obviously) particularly high stress or alternating compression-tension stress.
I ask as I will be looking at this bottom flange & web crack...
Hi all,
If you have any good references for the behaviour thin sheet (~0.4mm) cladding behaviour for roof/wall diaphragms I'm interest in advice or links. Thanks in advance. [2thumbsup]
(In general I don't consider such cladding as part of my structural load path in my designs. But in...
Hi All,
As the subject says what are your software recommendations for somebody wanting to do basic structural drafting for residential projects? I'd prefer to use something more simple and modern that AutoCAD.
Essentially my workflow will be:
-importing architectural DWGs and stripping them...
I thought I'd share this. It is neither a question nor so I present particularly insightful commentary on it. I just though that it was a beautiful combination of art and mathematics into one of structural engineering's oldest challenges, bridge design. To whet your appetite. The openable...
Hi all. I though I'd reach out for ideas and tips on improving my workflow particularly with respect to using a iPad or similar tablet to mark up drawings. My main needs is to be able to quickly edit and annotate PDF file drawing which will then be saved and sent to be more formally drafted by...
One thing that I've often been curious about is the buckling behaviour of a nominally pinned column under compression with a typical 'pinned' base plate.
Examples:
For both of these I would consider these as 'pinned' connection and model them as such. Thus I'd would get zero moment transfer...
Hi all. I though I'd throw this question out to the masses for a few ideas.
I need to seriously stiffen some members due to some vibrational issue. Cost of steel isn't really the issue it is more labour and looking for the easier and quickest solution to stiffen some existing beams. I'm...
Hi all,
The title says it all. Does anybody with experience in this area have recommendations for good books and references on silos. In particular steel sheet silos, Eurocode preferred. (A brief google has come up with a few, but I'd like to here recommendations if people have any.)...
Here is a question I thought I'd throw out to the masses. I'm after what people find as the most effective/economic solution to a structure of the form:
-Steel framed, open section beams and columns
-Braced frames for lateral restraint
-Multiple stories (let say 3-8 stories)
-Industrial setting...
It would seem that AS4600 has some pretty onerous limitiations when bolting steel sheet together. I'm considering two lapped plys of steel bolted together and the loss of capacity you get compared to say the EU code is significant.
