Dear Sir,
I would like to ask your help or any hint in the procedure i have to follow to calculate the truss member forces.
Consider all distances as given, and also all forces that are externally applied as given.
The two supports are unknown (2 hinges)...
Dear Sir/Madam,
For a 2 storey garage that will have traffic of 8tons cars (max gross weight), i would like you to help me to the following:
According to Eurocode 1,there is a use of a characteristic single axis load Qk that should be considered during the design. SO, my question:
How is it...
@rapt: Forgive me, it was my humour. The basement will have an automation system with two small spiral conveyors, that lead to the "±0.00 level" floor.
There are 5 storeys of 3 boxes per span of 10kN per box. A 5% increase factor is applied due to the structure selfweight. And this is divided by 4 footings.
So its 5*3*10*1,05/4=39,4 kN per foot.
BUT: in worse case footings (middle ones), it becomes double: Here is the exact analysis of...
Thank you @jayrod12! Beams and slabs can be increased in depth of course. Don't worry, The results i attached are only images: is the required reinforcement, longitudinal in both direction and required shear reinforcements of the slab. Not calculations :-P
Dear Sir/Madam,
On top-slabs of a concrete basement, 60kn/m2 will be applied (racking systems plus forklifts). I would like to tell me your thoughts, based on your experience.
My first approach is 30cm slab, with shear reinforcement. Beams 70x70cm (see attached) I analyzed the system and I...
Forgive me, this is the correct section:
It is 10m, not 5 of free height. But i got the point.
What safety factor would you apply to these point loads ? They are pretty exact,(The racks will have a 1,1 safety factor in their design) But i can't find it anywhere on Eurocode.
Forklifts FL3 type...
@ThomasH
The real load of pallet and forklifts is known(see attached image of first post). But i can't find nowhere in Eurocode the safety factor that the load should be multiplied with.
@HTURKAK
-The UDL load is at ground level, above a conrete basement.(see image)
-Rack location is frozen...
Dear Sir/Madam,
In an industrial building, there is a floor of pallet racket systems and forklifts (FL3 type).
The UDL load that i was told to take in the analysis is 60kN/m2.
Question:
What safety factor is applied to this load by Eurocode? I couldn't find for "Industrial use (E2)".
Of course...
Yes, an IPE 450 seems ok according to the software. XD sorry for asking your opinion guys, thank you!
If i could, i would use a truss, but its not possible due to architectural reasons
Dear friends,
i have a span of 18m. (see image below).
The purlins are in a 1,5 distance carrying a load of 2,2kN/m each.
I analysed the system using my software. A HEA 400 seems to be enough. But...i am new, i would think more reasonable a IPE450-500, and would like your thoughts/suggestions...
Dear Sir/madam,
i am analysing a structure that has a big span of 30m, so i think trusses (of the roof) are unavoidable, and the columns needed are HEB type.
Most trusses (of SHS section)that i have seen in my short engineering life are just lying above concrete columns.
Do you think that...
Dear sir/madam,
i have to analyse the attached curved structure. 5x5m approximate dimensions per span.
Which parts of the Eurocode would you refer into to calculate the wind load and the snow load?
I would choose:
"Figure 7.12, par.7.2.8 Vaulted roofs and domes-domes with circular base" of...
Using company's software i can calculate Vrd1 .
Using Eurocode 2, Fig.6.13 i can calculate Vsd
:) I think and hope that problem is solved! Love you guys and thanks!!!!https://files.engineering.com/getfile.aspx?folder=40d37b77-7856-4e52-b0f8-128faa3dd9db&file=Cross_section.pdf
