Rafter Collar ties
Rafter Collar ties
(OP)
Hello everyone,
I'm trying to design some rafters' collar ties on a new roof. Rafters are 2x10 rafters @ 24" OC, and it spans 12.75'The roof pitch is 6:12. Collar ties are located 1/3 from the ridge board. Please see the file attached.
Can someone please help me to understand what the most effective method of sizing these structural members is? I want to understand how the manual calculations are done too. I highly appreciate your help and time in this matter.
Thank you so much.
Best,
Myla

1. It is not possible to understand how to size collar ties without understanding their purpose.
2. Do you have rafter ties at or near ceiling level?
