very informative, thank you. I am building a room with hip roof using steel structure. Does the same rule apply as using timber? Also, the strength of steel is much higher than wood, do I need to consider different size for HIP rafters, and Ridge? I can not find anywhere a guide for the spacing of the common rafters Is there a rule to follow? thank you.
The calculations are the same for steel or timber in terms of cutting the rafters. Regarding sizing the members and layout spacing, try consulting span tables. I typically use the IRC (International Residential Code) but you can find others on the internet. Personally, I try to use 24" o.c. layout (as long as span allows) for cost savings but more conservative architects prefer 16" o.c. which provides more nailing surface for sheetrock.
Hi Steve, I'm using Autodesk Revit Architecture 2013. A very deep and expensive program however, if you are a teacher or student you may be able to buy it at a substantially reduced price as I did (visit www.creation engine.com). Please note that the rafters used in the video are not part of the in the box "families". I spent a yuge amount of time creating a suite of parametric rafters in preparation for the video. Hope this helps.
thanks so mucho bro
Excellent exposé!
I like learning how to do it myself for making my own
