@pth_steel_construction: Lateral displacement of rafters ( Lateral Torsional Buckling ) Designer already consider in design with Flange Bracing but Erector doesn't install it properly. This is Erector's mistake. During Install Rafter must install Purlin and Flange Bracing before release crane. In order to make structure more safe and stabilize we should add temporary cable bracing . Any Experience can share more in comment.
