oa Civil Engineer in South Africa - Implications of limit-state provisions in the proposed new South African code for steel design
This paper describes the proposals for a limit-state formulation of a new South African code for the design of steel buildings. During the development of this approach a number of anomalies and potential sources of confusion became apparent in ensuring consistency with the British interpretation of limit-state principles, as embodied in the South African concrete code. A framework is provided for a critical evaluation of the inflexibility in the present practice, and an alternative formulation is identified. The recommended approach to load combinations and conditions of overturning and stress reversal in the propsed code is also discussed.
