How to calculate Weight of steel structure 2

[AliNaseem2]

Hi, I am working on a project where we have to erect a steel structure for capacitor banks, I need to calculate weight of each part of steel structure for erection, Weight of each piece needs to be put on lifting certificate and calculate safe working load.
I tried looking online but can't get my head around it, I am an Electrical Engineer by trade & have no experience with structure, we have no structural or civil engineers, we have Supervisors & iron workers who can do the Job, but they are stumped on how to calculate weight.
I have reached out to design & fabrication team but they are no help.
I have attached link to some resources.

It really isn't that hard. You seem to have all the necessary drawings there. Just multiply the weight of the member per length by the length to get the weight of the member. Find the weight of the members from google or often even the member description.

Its pretty simple. Find volume (Area x length) of steel frames then multiply with unit weight.
Unit weight of steel is 7850 kg/m3.

W12x6.5x26 = 38.7 kg/m
W12x8x40 = 60kg/m

If you have access to the latest AISC manual for steel construction, it has tables for steel shapes and weight (in both metric and imperial units), also the weight pf connection bolt and nut. I think you know how to do the calculation, just lack resource material.

I'll one up you. AISC has a free excel shapes database you can download. it'll have all the information you need including the weights of the members in pounds per linear foot. All you need to do is figure out the lengths of the members and multiply by the weight. Boom.

[edit] I don't think the purlins will be in AISC though. You'll have to do a google search to get product data on those.

EDub24: and using that database and Excel, you can write something like... (edited today to include weight) You can cut and past rows 38 to 84 for new beams... I print them using DoroPDF for my project notes...
