![]() ![]() ![]() I ask this because with a strong connection between rafters / collar ties & rafters / ceiling joists am I not essentially recreating a framed truss ? With this logic, could the exterior walls be sized to mainly support 1/2 of the vertical roof load, and eliminate the need to provide roof braces along the ridge every +- 6 feet. The input I am hoping for (assuming I am not using a roof truss system for the garage and that the enclosed attic will be for access only, not storage) is if I am able to design a shear connection between the rafters and a 1/3 height placed collar tie as well as a shear connection between the rafters and the garage ceiling joists as a means to satisfy the thrust the roof would want to place on my exterior walls. For simplicity sake, we will consider the wall that the garage doors are located on as the x-axis, and the direction of the roof ridge as the y-axis. The structure in question is a simple garage (attached to a 2,000+- single family home) with 24'x24' overall dimensions. ![]() It is my understanding that in situations like the one I am about to describe, the savings in labor / current state of the supply of materials may make a roof truss become the most applicable option. Good afternoon everyone, I was hoping for a discussion on the expertise / applicability of choosing a roof system based on structural serviceability. ![]()
