roof trusses

[danilo]

i ty to do this more easy way rather than drawing by hand . any suggestion of how chief architect can actually do this properly ? chief architect keep doing all the trusses in the wrong way. 

[danilo]

thank you. I'm actually used chief 14 pro and i some of this detail i need to use different programs. any way we can do this on chief architect pro14?

Looks like a standard hip truss?

The geometry will probably change depending on your sizes, spans, etc

You can always edit them with fine tuning in the Truss Detail

When I went to the UGM in late August I discussed the trusses with the guys.  

 

I do not believe CA does trusses correctly......  at least the way we do it in the land of ........ 

 

CA believes that there is a HIP TRUSS.....  a trusses that takes the place of a HIP BEAM.

 

Does anybody else agree with me or do you guys do it the way CA creates hip set trusses?

 

If you do not agree with me,  will you please post a set of your truss calcs that detail a HIP TRUSS (takes the place of a HIP BEAM).

I've never heard it called a beam, but i'm not a truss guy, but it is a singular member in the sample i checked, and for this case it is 2x6

 

 

 

C-1,C7, are single members

yea,  you and I are same page,   BTW,  T-1 is typicallly a double truss…….

 

C-1 is not a truss…..  it’s a 2X6……. Truss chords are typically 2x4’s

Here is a diagram of the setup in Oz.

I should have referred to my example as a Truncated Girder Truss.

Note the use of hip trusses.

This is a diagram from the Pryda manual - they are truss manufacturers.

Keep in mind that trusses vary significantly by region, loading conditions, manufacturer methods, and customer preferences. Typical to you and your region and your experience is probably not typical to someone else's. Although, I must admit, you are in the largest market in NA, therefore your 'typical' may trump my earlier statements!

I think what Scott is talking about is what some in the truss biz call the California hip.  I've seen it in pictures, but not in the field.  In the two places I see builds, SW FL and upstate NY (two very different snow loads!), hips are done as per the arrangement in the lower half of the page, attached.  Commons, stepdowns, girder, hip trusses, monotruss jacks across end and down the hips which are trusses.

 

The CA way is to run a hip "joist," not a truss, but a member just like in a stickframed hipped roof, down from the girder truss and across the corner.  This is what DSH is calling the hip beam.  Note how the monotrusses have bottom chords that go under the hips and over to hang to the girder.  Those monos and jacks are not triangular-built trusses, and I've no idea how they are handled in the field.
