Hey everyone!
There's a possibility I have to design a large manufacturing building with external dimensions of approximately 141x182 m. It'll probably have RC or steel columns, steel trusses for roofs and metal deck on top of these trusses. The building also houses a lot of cranes, a few of...
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.
...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 factory that produces like live stock feed pellets - this is a second factory, the first one was...
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...
...reaction from all this is 300,33 kN - which corresponds pretty much exactly to the weight and volume of the vertical section of the silo: V=6,415*2,0*2,6=33,36 m³, weight of grain 9 kN/m³ - total weight G=300,24 kN. But where is the weight of the filled hopper taken into account - the hopper...
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) ...
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...
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.
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...
