COMPUTERISED DESIGN AIDS FOR REINFORCED CONCRETE

This article focusses on the use of the computer with special reference to certain New Zealand developments. Before the arrival of compact and relatively low cost computing power, charts and tables were the most appropriate means of determining steel requirements. Designers can now implement directly the algorithms used to produce these charts and tables in the first instance. Other facets of the design process can also be included. The author outlines the facilities of three suites of computer software currently in use. Two programs relate specifically to the design of concrete columns and the third can relate to beams or columns and can be used to assess the adequacy of a given design solution. The strain hardening characteristics of reinforcing steel can also be taken into account. Rectangular and circular sections subject to axial load and to bending about one principle axis are dealt with. Biaxial analysis can be accomodated in one of the programs. There is considerable flexibility in the choice of material properties, shape details and amount of reinforcing steel. Incompatibility of strain between components can be taken into account in the analysis. (TRRL)
