How We Design a Truss in Our Engineering Office - Part 1

[@behzadtaghipour6394]

Great Job Mr. Engineer, really appreciate it, the contents you create is rare to find! better than any course i had about Truss! Thanks God Bless you

[@bengthebrazilianengineerinAus]

Thanks for the feedback :) Glad it was helpful

[@JJBeast41]

You’re videos are amazing man. Im in my final year of my degree and im working for a structural consulting firm here in Canada, Ontario as a designer. Your videos on connections and general stuff like this are really great to watch on my downtime.

[@bengthebrazilianengineerinAus]

Thanks Jonathan. I appreciate your support and all the best in your career as a structural engineer.

To able to use "I+A*d^2" formula the section of the beam is constant/continuous/not interrupted by space. I think you should use the formula "Sum(A*d2)" for second area moment aka I.

[@bengthebrazilianengineerinAus]

Yes, the formula is always the sum

[@Machozz]

How to decide the depth of a truss? Lol whatever the architect say the limit is or less.

Amazing work brother.. thank for providing this valuable content 😊

Thanks my friend. Appreciate it :)

I am lost to finding the value of d. My question is, what is the value of I you used and where did you find it?

[@bengthebrazilianengineerinAus]

The I value of the PFC is on the table. See 6:58. I bring up the table. If you are using a different section, your I value will be different. The other I value (for the truss system), I found in the beginning of the video by rearranging the deflection formula for a simply supported beam. To find "d", I simply rearranged the Parallel axis theorem formula.

[@johnnytruth9271]

thanks for sharing. quick questions, have you seen a concrete pad sitting on top a bored pier so a steel column can sit on it? they then become part of slab when the slab is formed? I just could not picture how it would look like.

[@bengthebrazilianengineerinAus]

I don't see a reason to have the pad in there. Is the column section greater than the bored pier?

[@johnh6798]

the column is to support the 1st level floor beam (2 story building)

[@amosoladokun5474]

Where can I get the design member capacities in axial tension and compression tables for educational purpose. Thanks

[@bengthebrazilianengineerinAus]

If you google design capacity tables Liberty you may find them. They are sections from Australia though.

[@designlife93]

Is it possible for you to give this tutorial using back to back angle? Would the process be different?

[@bengthebrazilianengineerinAus]

same process

[@anonymouscommenter8637]

what is the app u r using?

[@patrickconner726]

Do you do independent work?

[@bengthebrazilianengineerinAus]

Hi Patrick, I do. Are you based in Australia? Send me an email and I see if I can help you. Thanks

Is mathcad free ? i downloaded it and after a month there is a logo on the page.

[@bengthebrazilianengineerinAus]

I haven't used it much anymore. It's paid. Maybe have a look at Smath? I think it's free

[@structurbay]

thanks sir

[@bengthebrazilianengineerinAus]

Thank you :)

[@manuel_youtube_ttt]

I would suggest to use the units in Mathcad, otherwise you are using a fancy notepad/calculator with images and formatting.

[@bengthebrazilianengineerinAus]

You're correct. I don't use much Mathcad. I know it's a good tool though. Do you use it at work?

[@manuel_youtube_ttt]

@@bengthebrazilianengineerinAus I don't use it at work. I've used it only for personal calculations. Although I've switched to do things in Python, so that I don't have to depend on commercial software (even though the free version is still super useful). The only downside is that I have to take care of units myself, but that's fine if I strictly only use SI units. Nice video!

[@poparafael3065]

@@bengthebrazilianengineerinAus I use it at work for some basic manual checks. Very useful!

[@bengthebrazilianengineerinAus]

@@poparafael3065 I haven't used it for ages. There's another free one called Smath or something like that

[@googleyoutubechannel8554]

Dear engineers, please for the love of humans, use any simple standard eng program if you need to model up a truss, this isn't a college exam, hand-calculating using the simplest (dumbest) possible truss model isn't a benefit, it's just risking all manner of subtle mistakes.

[@bengthebrazilianengineerinAus]

wrong
