Concrete Portal frame
Concrete Portal frame
(OP)
Has anyone ever designed a concrete portal frame?
If so how did you go about designing the column to rafter transitions/connections?
Is there any literature on this at all?
Thanks all!

I will look into Strut and Tie method. Hokkie66 is this method used frequently here in Australia? Are concrete portal frames used much here also?
Gyroman10 where is it possible to get Bagash "Structural Details in Concrete" from?
RE: Concrete Portal frame
Concrete portal frames are rare here, I believe. It would be interesting to know your application.
RE: Concrete Portal frame
I see Warner, Rangan at el has a whole chapter on the method.
I'll look into it. Obviously the method hasn't been around all that long right?
RE: Concrete Portal frame
Been asked by a precast concrete firm the merits of using concrete portals. I agree concrete portals not used much here.
RE: Concrete Portal frame
There are lots of pitfalls in designing for the forces around a knee in concrete. I try to avoid this type structure, and am very conservative if forced into using one. As well as the strut and tie information, read the Chapter in Warner "Guidelines for Detailing". Makes you very wary of this type connection.

civeng80 i am sorry i dint find the book on any internet book store, i bought this book from amazon.com 7 years ago.
RE: Concrete Portal frame
Very interesting your span is about what Im looking at at the moment. I note that the portal is in two parts and pinned at the ridge point. Just wonder how its erected and the roofing material and walling was it all concrete or metal?
What sort of dimensions did he come up with for beam and columns??
Cheers!
