WebBuilders should consider installing the following: Install steel connectors, strapping, or screws at roof-to-wall connections to increase the uplift resistance along the load path. Secure roof sheathing to rafters or trusses using dense screw patterns, clips, and straps to increase the uplift resistance. WebDevelop a STM - a truss system to represent the stress flow through the D-region and calculate the member forces in the truss. Design the members of the STM - dimension and design the truss members to resist the design forces. Iterate to optimise the STM as necessary to minimise strain energy.
