oa Civil Engineering = Siviele Ingenieurswese - A survey and comparison of beam-column approaches



There are a confusing number of beam-column approaches in present steel and concrete design codes. This paper critically compares uniaxial beamcolumn 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 ofthis paper is to make practising engineers aware of the many divergent presentations of such beamcolumn design provisions in current design specifications and to encourage the use of alternative design methods, instead of the common enective iengthbased approaches. One such alternative method, recently developed by myself, is included in this paper for comparison purposes.
