<p>An improved bracing system for a building system having a primary structure on which are supported secondary structural systems such as purlins, a tertiary structural system supported by the secondary structural system, and a first bracing system which interconnects a selected portion of the tertiary structural system to the primary structural system so that the tertiary structural system is restricted from translational and rotational movement as the tertiary structural system is subject to load and other of the tertiary support systems are allowed to flex with their elastic limits as the roof expands and contracts. A second bracing system interconnects to and extends between a portion of the secondary structural system and the primary structure so that the secondary structural system is restricted from translational movement and from rotational movement as the secondary structural system is subjected to load.</p> |
