Design of Steel Roof Truss in ETABS

This tutorial discusses the modelling and design of steel roof truss for industrial buildings, warehouses, parking lots and markets. This video explains about the complete information which is useful for the design of a truss. In this video following topics are covered:
1) Basic theory and application of truss
2) How to select type of truss for our design
3) Modelling of truss in ETABS
4) Extracting load values from the code
5) Understanding the analysis results
6) Economical design of the truss

Thanks a lot. Great video. Good narration. Good voice. very clear and complete. Looking forward to watch other videos from you. Best wishes!

[@shakiltadvi1049]

Amazing tutorial.Sir can you please provide connection design tutorial for the same truss.

[@Hanns_designs]

Thank you bro, learning alot from you

[@heidenfelderkustoms1502]

Do you do design work for home shops? I want to add a loft and lean to on my existing structure.

Sir , In video the assign the relese to the truss member is skiiped ,

[@kelvs526]

How do you assign windload on 1 slope shed type roof? What is the direction of windward and leeward?

[@beenay18]

I have a problem. When I draw a shell and assign null as section, and then apply shell load on it, it won't transfer the load to the beams and columns below it. How can I apply area loads avoiding the self weight of the shell element? Looking forward to get answer from you. Best regards.

Great Video Waiting For More Informative Tutorials... Sir If possible Can you cover a tutorial on steel Building Design Which consit of BRBF ,EBF, SCBF as per AISC 360 & 341. Thanking You In Advance 😊

[@anousitvlv]

Dear could you help me that why axial force of top and bottom chord of my model are so differently (around 72% of difference), but when i assign load on top chord directly, the axial force of top and bottom chord are quite closely.

[@anishpandey6573]

Can you explain how you take windward coefficient as 0.8 and leeward coefficient as 0.5. Since as per code there is Cpe and Cpi (external and internal pressure coefficient)

[@alihussnain8569]

I am facing extruding shell issue. On left side, the shell is being extruded on the lower side while on the right side, it is extruded on the upper side.

[@beenay18]

I have a question. When you imported the steel sections, the section shape was indian but the default material was A992Fy50 which is American standard material. Fy of A992FY50 would be 355 Mpa is SI unit. I have seen people changing it to Fe250. Shouldn't we do that?

[@rabinderladhani1294]

You can change it accordingly.

[@astmcivil]

if we select the auto-selection property for the truss top and bottom member and for the column it is a better way for steel design. by useing the auto-selection property program to collect economic section for all members

[@fullscale58]

I just designed a warehouse through auto beam n columns everything seems good except columns all columns have failed what could be reason behind this..?? 🤔

[@AshwanikumarSainiARTER]

nice tutorial. Yes connections are important and I was wondering how you connect everything together. e.g. purlins over trusses.

[@azmat_waseem]

Very Informative... Thanks....

[@fullscale58]

I just designed a industrial warehouse where I took ISMB 600 (as columns) but all columns are fail. Can anybody give idea what could be reason behind this.?

[@paradigmengineeringconsult3449]

Dear sir, You are using the pressure coefficient value of Cp=-0.8 and Cp=-04 . Where do you get it from?? I have found different value from IS 875 Part 3 .

[@structguru2200]

Its 0.8 and -0.5. This also depends on L/B ratio (L= length of the building plan and B= Width of the building plan)

[@paradigmengineeringconsult3449]

@@structguru2200 Which code you are using??? IS or ACI??

[@structguru2200]

This is same in both ACI as well as IS code.

[@edmundtumaca2334]

How about a steel truss resting on concrete beam, how we do model the connection and what R value should be used for seismic.

[@beenay18]

I think you forgot to show how the moments in the truss joints are released. Is it ok to select whole roof and assign the pin joint constraint?

[@rabinderladhani1294]

I wanted to cover moment release topic in other video tutorial. Due to unavailability of time I am unable to post videos.

[@beenay18]

You also skipped assigning diaphragm to the roof. Can diaphragm be assigned to inclined shell element? Please make a video on that subject.

[@lossfreetrading996]

Good 👌

[@structguru2200]

Thank you! :)

[@roshankumar-ee2jh]

Why is wind load not assigned to columns?

[@arpitjaiswal5266]

What about the wind load from other direction.

Thank you!

[@ajazsayyed8487]

Best sir. I saw truss member releases In some of video plz comment on it.

[@structguru2200]

Thank you Ajaz! As truss is an axial member so we have to release the moments. To release the moment you can refer to my video kzbin.info/www/bejne/nJ7Cp3pjjtuIoaM. I will cover the moment release topic in detail in upcoming video in connection design.

Very lucid video. Your video has been interrupted. In order to release the moment to act as pin jointed, how will we release the moment?
