Stability in steel building construction

The girt is commonly used as a stabilizing element to the primary structure (e.g. column, post). Wall cladding fastened to the girt, or a discrete bracing system which includes the girt, can provide shear resistance, in the plane of the wall, along the length of the primary member. Since the girts are normally fastened to, or near, the exterior flange of a column, stability braces may be installed at a girt to resist rotation of the unsupported, inner flange of the primary member. The girt system must be competent and adequately stiff to provide the required stabilizing resistance in addition to its role as a wall panel support. Girts are stabilized by (sag) rods/angles/straps and by the wall cladding. Stabilizing rods are discrete brace members to prevent rotation of an unsupported flange of the girt. Sheet metal wall panels are usually considered to provide lateral bracing to the connected, typically exterior flange along the length of the girt. Under restricted circumstances,North American Specification for the Design of Cold-Formed Steel Structural Members sheet metal wall panels are also capable of providing rotational restraint to the girt section. In general: Girt supports panel, panel stabilizes girt; Column supports girt, girt stabilizes column. The building designer should be knowledgeable in the complexities of this interactive design condition to ensure competent design of the complete structure.
