Principles and application of structural design code development in South Africa
Structural design codes reflect the customs in construction, available materials, training and other characteristics of the regions from where they originate. However, owing to globalisation, and a worldwide trend in which structural design codes are being harmonised, the application of international codes locally requires a proper framework and guidelines in order to match the implicit basis of these codes to local conditions and requirements. South Africa is in the process of revising their suite of structural design codes, and has opted to use the Eurocode suite of codes as reference material for this process. Inherent differences between the environment in which Eurocode and such transferred codes will operate makes it imperative that local implementation be based on a fundamental approach of code development. The paper presents a scheme that can serve as guidelines for code development, based on a set of attributes serving as the driving potential for the process, within the context of the technical nature of structural design codes, some meta- technical characteristics and organisational relationships. The application of the scheme is demonstrated by showing examples of how selected Eurocode standards are applied as South African codes.
