thanks. Yep, I had actually just tried that equivalent E x x I value from a Corus ref. for Design Guide for SHS concrete filled Columns.
Thanks for the AISC references.
I have a 10m column, 1m dia 10mm thick. I need stiffen it by filling it with grout. How do I model that combined property? One member with the equivalent stiffness (not sure how) or model an unreinforced conc column and put rigid links to the steel column?
Modelling deck plate. There's a way to do this, but I can't remember:
Say 1m c/c x 2m, and 6mm thick, I can take an effective width of plate and model it as a truss element across the diagonals, bd3/12 for an effective Ivalue, and give it zero density?
I'm sure that modelling the full plate...
New mild steel guide , clamped to +9m brace. Retrofit superduplex caisson. Probably have a 25mm anulus. Is a rubber liner to the guide barrel adequate for isolation? PTFE? 20year design life.

Designing a dump caisson. Terminates LAT+6. Can't remember what reference to look up for what corrosion allowance to apply to the minimum wall thickness. Any advice appreciated.
I'v ebeen asked toconsider galvanising cold formed tubing for handrails. typically Hybox 355 42mm x 4mm . It will mean bending to a radius of approx 300.
I'm concerned about the possibility of cracking that may lead to premature corrosion of the rails. I belive the most vulnerable part will be...
Age old lock nut query:
I’ve a 300(+ more as required )mm long M30 Grade 8.8 with a 200roller (or boss)and connecting lugs at each end of the roller. I need to fasten the bolt (or stud) so that it doesn’t rotate (as it will have a3mm dia hole drilled half way through its length for greasing...
I'm trying to find a reference for how much to load test a lift installation aid.
lift load 10 tonnes, suspended from a padeye that is welded to a temporary lift beam. The temporary lift beam is bolted (lindapters in tension) to existing deckbeams.
THere's a table somewhere that i've seen that...
can anyone recommend a glue / epoxy resin for fixing machine plant footings to steel deck plate? it's for a no-hot work area. the other alternative solution is for sort of single sided bolts.
i'm looking for examples of cladding and flashing finishes for where cladding , flashing and foundations meet. been searching for examples to confirm / back-up my solution and have started tearing a few hairs out. probably an architectural database or online forum or similar would be useful...
is there a global Cpe (exteral wind perssure) for roof loading?
i'm determining wind loads on a 15 x 30m x 8m high shed with a 12 degree pitched roof. I've just waded through all the local pressure co-eff checks, Fig 20 etc. is there a quicker way that i have missed to generate wind loads for...
