Abstract:
A new British standard for steelwork is being drafted incorporating much of the research done since issue of the present British standard in 1969. The variable-stiffness method, the latest available method for column design in rigid-jointed steel frames, is described in detail. Application of this method in the design of reinforced concrete columns is then discussed. Various methods are progressively given covering the design of short and slender pin-ended composite steel-concrete columns when subjected to axial load only and to uniaxial and biaxial bending. Simplified design methods are described for the last two cases.
