Another morning, another questions. Would steel bars (I'm thinking 8x70 mm or something) instead of angle sections for stiffeners be okay as well? The manufacturer didn't like the angle sections too much - they thought painting them would be a bit labour intensive.

Thanks for the tip :)

Even about 65 mm seems quite a lot to me :). So is it normal that the walls bulge out this much?

I'll ask a few more questions then :) Can you give some advice on what the most sensible sections to use as stiffeners might be for this kind of silo? I think I'll use 4 or 5 mm steel plates as main walls and some angle sections (currently L70*7) for stiffeners. The silo I'm designing is for a...

Thanks! I actually see myself that the normal loads are the ones that govern the design. The other questions are more like just for knowledge. And a pink star has been awarded :) Though I think it's already a second one for you - I think I added the first one on my phone and perhaps it didn't...

I did, the discharge loads are governing for this case. I used the formulas 6.24 and 6.25 from the code for this: I did use the factors for the wall friction coefficient, lateral pressure ratio and angle of internal friction according to table 3.1. The loads applied in the model for case...

Since you are so experienced with silo design I'll annoy you a bit more :) I've calculated the loads, took some time to make an Excel sheet for this stuff, and am now trying to apply them in my SCIA model. A screenshot below (don't mind the missing stiffeners for the hopper, I've not modelled...

Thanks for great answer! But in your experience would`it be correct to assume hinges between the vertical connections of the 2D walls in the calculation model?

Hello everyone! So I'm designing a steel grain silo with a capacity of around 33 m³ for the vertical part (class 1 according to EC 1991-4, under 100 t) - the cross-section is 2,0x2,6 m and the vertical section is 6,75 m high (so the grain would weigh around 300 kN at a unit weight of 9 kN/m³) ...

At least the technical documentation for the machine I have does not mention any.

Many thanks! I think I'll still go with the high IPE400 beams just in case.

Thanks! I read from the link you posted that elastomer dampers where eventually used to reduce the vibrations - does this mean the support beams where not stiffened at all then? And can you please specify how the dampers where detailed? Also in the thread you posted someone's advice was to get...

OP here. Received a little more info on the machine. The "6 pol 50 Hz" does indeed mean that it is a motor with 6 poles operating at 50 Hz as many of you thought as well. It is a screening machine/sieve for separating grain, I think. It has four supports with some dampers as well (in red on the...

It's some sort of a grain grinding mill I think.

Hey everyone! So I'm designing a factory that has a vibrating equipment on one floor. The load is given like this: Do you have any thoughts what that "6 pol" might mean? I'm not too familiar with dynamic analysis but am trying to educate myself a little in Robot Structural Analysis.

I was not asking about this. I was just looking for some ideas on how to detail these connections.

Hi everyone! Perhaps you have some helpful suggestions. I'm designing a facility that has some wheat silos on top of sway frames. The frames itself are about 7 m tall and span 5 m, but the loads from the silos are really large. In my calculation model all the joints are currently hinged. Below...

I meant in-plane buckling. It will have compression as well. But what do you mean by design method?

Hey everyone! What the buckling lengths for member B6 and the top half of B7 should be? All supports are pinned and currently connections between the beam B8 and its columns are pinned as well. B6 is about 13 m high.

Hey everyone! So the contractor wants I design a roof with a two-sided 6° inclination using hollow core slabs - he thinks he'll have easier time with the insulation this way. Below is a preliminary section of the building. The yellow ones are hollow core slabs that span ~7 m and they are...
