Cold-formed steel (CFS) sections are commonly used in modern building construction. When used as secondary roof purlins, CFS sections are often attached to trapezoidal sheets through self-drilling or self-tapping screws to form a complete roofing system. The hat shaped cold formed steel sections are commonly used as batten member in light-weight steel constructions, such as residential, industrial and commercial buildings. Failures of the connections of thin-walled steel roof battens to rafters or trusses were increasingly observed in the form of a localized pull-through failure in the batten bottom flanges during recent extreme wind events. Therefore, a detailed numerical study was undertaken by developing suitable finite-element models with the inclusion of a suitable failure criterion to predict the initiation of critical pull-through failures of roof battens. The failure load value of batten is taken from previous experimental results as a base criterion. For this load total deformation, equivalents stresses and maximum principal stresses are compared between all the proposed models. First the analysis is carried out for some existing strengthening methods and then analysis of proposed methods is completed.
