oa Civil Engineer in South Africa - A survey and comparison of beam-column approaches : technical paper
There are a confusing number of beam-column approaches in present steel and concrete design codes. This paper critically compares uniaxial beam-column design provisions in limit state approaches coupled with an elastic structural analysis. Such analysis and design are the most popular in design offices. The aspects of lateral-torsional buckling and local stability (web and flange buckling) are excluded from this study. The object of this paper is to make practising engineers aware of the many divergent presentations of such beam-column design provisions in current design specifications and to encourage the use of alternative design methods, instead of the common effective length-based approaches. One such alternative method, recently developed by myself, is included in this paper for comparison purposes.
