I am currently learning it. The modelling appears very fast. It uses almost revit structure. STAADpro is begining to take too much time for me to deliver.
is the modelling like prota structures?

I've not seen prota but it has similarity with revit. You use revit structure?

Hi Hakeem
I have installed Staad pro CE update 4
But the physical modeler does not work
Please can you help me to fix the problem
Greetings

I have a steel problem o. I am designing a 30m truss and ending up with a very heavy angle section. Anyone have a way I can reduce it or get a more economic section?

Why not change it to I or H beam? And also, try double angle or Channel section. And above all, I hope you used the required height for the truss? And more so, what type of truss? You should use a parallel chord truss for that span.

use back to back angle (double angle) as yungmin suggested. Must it be a truss? Why don’t you try portal frame or linto roof style

Can't use a H-Beam. I intend to use a double angle section like you posited. The truss is a sort of combination between warren and Pratt, see attached diagram (450mm and 1500mm).
I would change truss type to parallel chord with required height and get back to you.

Can a 75x75x6 double angle section replace a 150x150x10 single angle section theoretically? Doesn't seem to work that way on staad or I am probably not doing it right.

Thanks.

I intend to switch to portal frame as a last resort if I can't figure the truss out, someone who doesn't use staad thinks it's possible to get something far lower.

30m span? try 2/90x90x6. ( I did not design it ooo) try and change all the compression bars to tension direction and they should reduce

Check the span / depth ratio to be very sure it is correct. Otherwise the members would continue to be very heavy. Pls reference truss design in the steel designers manual. Also explore portal frame system as suggested by @Hakeem.

Thanks, yes I am referencing SDM.
I'll appreciate if you can do justice to that question above on single and double angle sections.

Bro, that section is still quite small. I did a 40m span mansard truss sometime ago. The sizes I got for both top and bottom chords where L200x200x16. You know if you are to use parallel chord truss for this problem, your span/depth ratio should be in the range of 15 to 25. In other words, you need a minimum of 2meters depth of the truss.

In the analysis I did for this, the lowest section I could get was L150x150x15. I intend using span/depth ratio of 10-15 for the parallel chord truss I would do. What did you end up using for the mansard you did?

This was the question I was referring to though. cc: yungmin

I tried to post the command file but NL said it was too long. I have attached the model.
I stripped it bare, no wind load.

Loads were applied on the purlins, I have another model where I applied the loads nodally and that was the one that gave the least section(L150x150x15) I have gotten so far

Thanks

sconp did the architect restrict your truss depth? can you reconfigure your truss members so you do not have too many struts and ties?

Yes he did, though he has said I can go as high as 2m now. The struts spacing are to coincide with the purlins, max spacing 1.5m

There’s no law that restricts you for your purlin spacings. Try and increase the spacing the forces would reduce from my experience. but don’t make your purlins spacing exceed 2m from practical POV

picture is a roof truss I design with 25m span. Purlins spacing of 2m

Nice I will try that.
Though at the moment 2L80x80x10 is able to take care of it.
