Tension in Roof Collar Tie

[karimom]

Hi All,

I am doing a repair for a roof and the span is quite long for a stick framed roof (42' w/ rafters at 16"o/c). I used the method of joints to determine I need ceiling joists to resist 14.42KN ~3.3kips.

Is there a better way of connecting them then using 30 some nails such as an off the shelf product or framing plywood/nailer plates. I'm drawing a blank on this one and would think there is a better alternative.

Are you clear spanning that distance or are you spanning that distance with rafter bracing? Is the 42' the wall-to-wall distance or the distance from wall-to-ridge?

Wall to wall

Seems like a tall order. Why is a repair necessary?
Can you provide a cross section showing member sizes and roof slope.
Any possibility of adding a ridge beam?
