Abstract:
Columns are an important structural element in reinforced concrete structures. They are usually cast integrally with the framing concrete beams and slabs although precast columns can be used in appropriate situations. They have to provide resistance to both axial forces and bending moments generally resulting from load applied to the floor beams and slabs. In the design procedure for columns, use is made of the load-moment interaction diagrams which may be in the form of design charts or generated by computer programs. The new AS3600-2001 design provisions for columns take into account the change to the higher strength steels. This paper presents the background to the changes and includes important explanatory information. This will assist structural design engineers
to understand the engineering principles on which the design method is based and to better realise the benefits that can be achieved through the use of the changes in conjunction with the introduction of the high strength steels. These benefits are highlighted through the presentation of a number of practical worked examples. Examples of new improved design charts are also presented.
