Hi all,
Recently I was given a task of reducing the spread of vibrations through a welded steel structure. I have attached an image of the structure below. Now the structure is approximately 10 meters long and 3 meters wide, it is supporting a vibrating conveyor whose vibrations are to be...
Thank you both for the advice.
I made some adjustments by eliminating unnecessary mansard trusses and adding some cross bracings to the lower chords.
As for the chord sizing 100x80x4 mm rectangular HSS seems to be able to handle the loads fine...
Thank you very much for the swift reply.
I agree on the 10%, and I have found that lower percentages can work given light enough loads, which is definitely not the case here.
Here we have a truss that needs to carry the weight of entire seven additional trusses in addition to the normal roof...
Hi all,
Recently a customer came to me with a sketch of a steel construction based around secondary bolted trusses onto a main truss (Sketch below). The main fixed demand is that the depth of the truss is 0.65 meters.
I personally found the truss depth of the primary truss (8 meters) to be too...
Apologies for the late reply, busy weekend.
@KootK
1) Yeah since I was planning on gap joints I was expecting some eccentricity and was planning to take into account the resulting moments.
I planned to simply add this to the axial forces per formula 7.5 below.
2) Why do you think my...
Hi all,
I am currently designing a truss with IPE 140 (I-beam) as chords. The beam however is rotated on its side, meaning its web is horizontal. The truss will have square hollow structural steel diagonals which are welded onto the horizontal web.
While checking those diagonals in the Eurocode...
@EdStainless
Several solutions including bars underneath crossed my mind too, but i couldnt figure out how a lever would move them out of the way.
Could you perhaps go into more detail or even better produce a simple sketch.
@hendersdc
This is exactly what I had in mind, thanks so much I...
Hi everyone, sorry for the late reply, I really appreciate all the answers.
As for your questions:
@desertfox
The box is to be used to transport ash with a forklift, the forklift would lift the box and a huge bag would be attached to the bottom through hooks on the side of the box (not visible...
I have been having trouble with a problem that looks really easy, I need to design a mechanism which can open the bottom doors( marked blue on the picture ) on this steel box in order to empty its contents, and of course keep it closed when the mechanism is not activated, the mechanism has to be...
