BS 5950-9:1994 gives recommendations for the design of shear diaphragms in light gauge profiled steel sheet and the contribution of such diaphragms to the strength and stiffness of structural steelwork in buildings and allied structures. It also gives design recommendations for the effect of profiled steel sheet in lateral bracing to members, diaphragm action in composite floors and folded plate roof construction. Worked examples showing the application of the method to several different design cases are given in Annex A to Annex H.
The recommendations may apply to shear diaphragms in any of the following positions in buildings:
NOTE These recommendations are based on the assumption that the materials and construction conform to BS 5950-7.
Executive summary
Recommendations for the design of structural steelwork in buildings using hot rolled steel sections, flats, plates, hot finished structural hollow sections and cold formed structural hollow sections.
Abstract
This British Standard, a part of the BS 5950 series, provides recommendations for the design of structural steelwork using hot rolled steel sections, flats, plates, hot finished structural hollow sections and cold formed structural hollow sections, in buildings and allied structures not specifically covered by other standards.
Recommendations are provided on limit states design, properties of materials and section properties, design of structural members, continuous members, connections and loading tests.
The test procedures in this British Standard are intended only for steel structures. The provisions of this standard apply to the majority of simple and continuous steel structures although it is recognized that cases will arise when other proven methods of design may be more appropriate.
