000012729 520__ $$2eng$$aA new approach to estimate the web crippling failure load of cold-formed steel beams under Internal Two Flange (ITF) loading using the Direct Strength Method (DSM) is presented in this paper. After briefly describing the test data to calibrate the DSM-based formula, the accuracy of the analytical expressions given in Eurocode 3 (CEN, 2006) and the North-American Specification (AISI, 2012) is briefly assessed. Then, several types of analyses are performed: (i) quasi-static non-linear analyses (using finite elements), (ii) elastic buckling analyses (using finite elements and the GBTWEB software), and (ii) rigid-plastic analyses (using yield-line theory). The coefficients of a DSM-based formula are determined on the basis of the set of 85 experimental results available in the literature and the corresponding buckling and plastic load values. It is shown that the proposed DSM-based formula for ITF loading yields reasonable predictions of web crippling loads and provides safe estimates of flange crushing loads.
