Authors: Pham, L., Carson, J. and Watson, K. / Structural design codes/manuals have evolved from ‘Codes of Practice’ (guidelines written by engineers for use by engineers) to ‘referenced documents’ in building regulation. Participation in the development of these documents has undergone considerable changes with gradual decline in contributions from the public sector (government departments, research and academic institutions). This paper argues that, for the Australian situation, the responsibilities for the structural design codes should be divided between private and public sectors. Responsibilities for building policy issues, such as the loading specifications and safety levels, should rest with Australian governments. Responsibilities for material specific design rules could be left to industry since it is in their interest to produce the best possible outcomes for their materials. This strategy will ensure the continuing development and sustainability of these documents. In: Australasian Structural Engineering Conference 2012.
