Hi.
I want to support my living room roof with round timber.
its a small roof by all acounts and the timber i have is treated spruce (class 1)minimum diameter 130cm. (this being the case i can use square timber calulations 130 x 130)
is there information that would help me calculate maximum spans for beams and purlins?
i would like to have an A frame and 2 x T frames if posible.
any input would be most helpfull
thanks
steve
