Numerical analysis of thin-walled cold-formed steel column-base over-roofing solutions

Abstract

In an increasingly developing world, in which sustainability has become not only an option but more of a demand, over-roofing of existing buildings, together with over-cladding form an optimum complete retrofitting solution. In this context, the paper is mainly focused on numerical analysis of cold-formed steel solution, in both semi-rigid and rigid solutions used for addition of new storey. Also, for ease in erecting, an option of column-base connection with chemical anchorage was analysed.
