TY  - JOUR
AB  - The importance of allowing for the many different types of structural interaction that have aneffect on the performance of light gauge members when used in practical situations isemphasised. A distinction is drawn between internal interactions involving the various plateelements of the steel profiles and external interactions involving the other components in thesystem. Although full-scale testing of representative systems can capture this behaviour, thecosts involved make this an impractical general basis for design; codified methods generallyconsider only isolated plates within members and isolated members within systems, therebyneglecting the potentially beneficial effects of both forms of interaction. Properly used,modern methods of numerical analysis offer the potential to systematically allow for bothforms of interaction – provided the numerical models used have been adequately validatedagainst suitable tests. The use of such an approach is explained and illustrated for threecommonly used structural systems: roof purlins, floor beams and columns in stud walls. Ineach case it is shown that, provided sufficient care is taken, the numerical approach can yieldaccurate predictions of the observed test behaviour. The subsequently generated largeportfolio of numerical results can then provide clear insights into the exact nature of thevarious interactions and, thus, form the basis for more realistic design approaches that areboth more accurate in their predictions and which lead to more economic designs. Buildingon this, modifying existing arrangements so as to yield superior performance through specificmodifications is now possible. Two such examples, one in which improved interconnectionbetween the components in a system is investigated and a second in which prestressing isshown to provide substantial enhancement for relatively small and simple changes, arepresented.
