UTILISING COMPOSITE ACTION IN LIGHT STEEL FRAMING
Light-gauge steel beams and wood-based boards are a popular and easily constructed means of providing floors of modest span.Present practice treats these two elements as separate for the purposes of the structural design.Tests on typical arrangements as well as some with more substantial interconnection between the beams and the boards have been conducted.These illustrate the potential for developing worthwhile levels of composite action that increase both strength and stiffness.The test data have been augmented by numerical results-validated against the tests-that provide the basis for a design method that follows the principles of the partial interaction approach to the design of steel-concrete beams utilising stud shear connectors.This method provides good predictions ofbehaviour at both the ultimate and the serviceability limit states.
