Hello, I'd like to ask the community a question on best practice to determine structural steel weights.
I have modeled plates, HSS and W sections structural steel railing (approx 33 meters in length) as part of an assembly in solidworks using a combination of weldments and parts. I can determine the weight of the structure by assigning a material from the SW library, however I've found that in the past the weights from the library tend to be low so I've taken to creating a custom material with a manually calibrated density.
The client has requested a tolerance of +/- 0.5 kg for the entire assembly.
I realize SW will calculate the mass based on volume, therefore the value will be highly dependent on density. The weight also does not take into account things such weight from the welding itself.
Could anyone suggest a best practice to compute the weight of a large structural steel assembly?
