This paper presents the results of a computational study on the stiffness requirements for shear diaphragms used for beam bracing. Doubly and singly symmetric cross sections were studied. The parameters that were investigated included diaphragm stiffness, load type, load position, cross-sectional shape, and web slenderness.

For diaphragm braced beams, Helwig and Yura (2008a) recommended that four times the ideal diaphragm stiffness be used for design. Since diaphragm braced beams are essentially continuously braced, the traditional definition of “buckling between the braced points” was not meaningful. Therefore, the ideal stiffness for diaphragm braced beams was

stiffness requirements for diaphragm bracing of beams Light gauge metal sheeting is commonly used in the building and bridge industry for concrete formwork. The metal forms, if properly attached to the beam or girder, often behave like a shear diaphragm and restrain the lateral displacement of the top flange, therefore improving the lateral-torsional buckling capacity prior …

In addition to supporting the concrete, the metal forms also improve the lateral-torsional buckling capacity of the beam or girder they are fastened to as they behave as a shear diaphragm and restrain the warping deformation of the top flange. However, the stability bracing requirements for shear diaphragms are not well established.

The stiffness requirement for the shear diaphragm given in Eq. (4) is based on an analysis of beams with an initial twist, θ 0= L b/(500d), where d= section depth and L bis the spacing between cross-frames. Helwig and Yura also investigated strength requirements for shear diaphragm bracing of stocky beams and proposed the following equation: =M r
