ABSTRACT

Cold-formed steel (CFS) members in buildings are in use for decades, but their earthquake performance remained unexplored, until recently. Eurocodes, which provide common approach for the design of buildings in Europe still lack the information on seismic design of CFS structures. However, for the last few years, University of Naples “Federico II” CFS research group is dedicated in investigating their seismic performance. One of the focus areas is characterizing seismic behaviour of CFS strap braced stud walls. This paper presents a generalized approach adopted in simulating hysteretic behaviour of these walls under cyclic load in OpenSees software. Numerical models are developed and calibrated on the basis of available experimental results.
