Description

This paper reviews the Component Stiffness Method for determining anchorage forces in roof systems as presented in Chapter 5 of the new AISI Design Guide for Cold-Formed Steel Purlin Roof Framing Systems. The four steps in the general methodology of the component stiffness method are presented. First, the development of forces requiring anchorage in purlin roof systems is discussed. Next, calculation of the stiffness of each of the components of the roof system and the procedure for distributing these forces through the system is presented. The final step, evaluation of the effectiveness of the anchors in preventing deformation of the system, is discussed. The five numerical examples relating to the component stiffness method are outlined.
