dc.description.abstractA Direct Strength Method (DSM) of design for cold-formed steel channels with holes in shear has been developed previously using a Vierendeel model. In particular, the model is applied to square, circular, rectangular and slotted holes. Although the model is accurate with cold-formed channels consisting of considerable hole sizes, the model is quite complex to implement into a design Standard such as AS/NZS 4600 or Specification such as AISI S100. In order to simplify the methodology, a cubic fit to the Vierendeel model prediction of the yield shear strength of the section with holes has been made. The fit equation is simply a function of the shear yield load, the hole depth divided by web depth and the hole depth divided by the hole length. The paper gives the development of the equations and a comparison of the method against a large range of test data in the literature.en_US
