1. Why didn't you model two purlin that runs like in real field? 2. Why did you break a both top chord and bottom chord at joint if it is single element in real field?
Thanks for your query dai, As i said we can model that purlin but there won’t be significant variation in result as i have done it previously. Secondly the basic idea of FEM is to subdivide member as possible it is. To generate accurate results for certain analyses, frames must be explicitly subdivided, or assigned automatic meshing, where the object is handled as a single member, but meshed into multiple segments for analysis purposes. Thanks. and do please let me know if there are some mistakes dai. Cheers
1. Its okay to do like that 2. For this case ;I think we can model as a single element as in field .But it may fail in slenderness ratio.For that we can overwrites the effective length parameter
For default load combination, do we have to ignore the load combination with negative Wind load (-WL)? Wind is supposed to produce uplift on the truss, but negative WL signifies downward force hence will be added to dead + live load.
In case if fully fixity is not achived, then rotation will be allowed in the joint which leada to failure. So just to be in the safe side design member with hinged support.
I thin you have not consider value of A for calculation of F....U have neglected value of A as I can see your calculation is F=(Cpe-cpi)xAxPd but in your sheet i dont see value of A.

Very informative for civil engineer
Thank you.
I am entersted in this course
Nice content daju and really thanks for such a nice effort
Thanks for your support.
Kindly make roof truss that includes snow load plz
Can you please do a vedio on connection design.😃
Sure.
For default load combination, do we have to ignore the load combination with negative Wind load (-WL)? Wind is supposed to produce uplift on the truss, but negative WL signifies downward force hence will be added to dead + live load.
We apply with direction of wind load and that will counter with the sign of load in load combination.
How can we check the load on our supports for designing of rcc column
I am intersteng in this coruse
Very Informative... Thanks...
So nice of you
While designing Truss can we consider bottom cord and inclined rafter as a single link. What happen if we do so?
You have to consider effective length ratio.
Sir 3 storey steel residensial building ko analysis plus design in etab and report preparing vedio haldinu na nepali language ma
Aba chittai aaucha hai ta
Sir kindly add snow load
How can we make the support as pin joint? Practically they will fix the support. Either they will weld in the base plate or they will anchor.
And Why K4 is not considered in this design. K4 is also explained in the code. When we consideted Ka, Kd and Kc?
In case if fully fixity is not achived, then rotation will be allowed in the joint which leada to failure. So just to be in the safe side design member with hinged support.
Importance Factor for Cyclonic Region (k4) . I hope you got the answer by the name of the factor itself.
@@civilconst Thank you for the explanation and the video tutorial.
CAN YOU GIVE ME THE EXCELL SHEET OF LOAD CALCULATION SHEET
At 6:13 you have already created struts, but again while creating inclined members you are joining the struct members again. Pls explain.
I didn't get your query. Could you explain a bit more?
@@civilconst Why are you overwriting existing struts while creating inclined members at the above timestamp.
Do you have online training.
How can we model roof truss for L shape building??
PLEASE SHOW THE FULL EXCEL SHEET IN U COLUMN
Can i get the excel sheet
why square section of 100 mm is not available,?

GREAT WORK CAN YOU SHARE EXCELL FILE PLZ
We can provide but you have to pay certain bucks for that.

i have checked DM, but it seems not everyone can send u msg in Instagram
I thin you have not consider value of A for calculation of F....U have neglected value of A as I can see your calculation is F=(Cpe-cpi)xAxPd but in your sheet i dont see value of A.
A = unit area for our case.
hellow sir can you provide me report file with excel sheet also..
We can provide but you it's no longer free.

Sir can we do this in etabs?
Obviously we can do. It is more easy in etabs. But you can’t assign uniform load to frame from area load.
can you provide excel sheet?
It's a paid resource. Please make payment first and will send you a link to download.
PLEASE SHARE THE EXCEL FILE
Please forward me the excel link 🙏
Write down your emai id
Pls send me excell sheet
