Cold formed steel constructions are, among the contemporary systems, one of the most competitive in terms of lightness, high structural performance, short execution times, quality of product and sustainability. This paper aims to summarize some important studies carried out at University of Naples “Federico II”, that investigated the feasibility of using cold formed steel systems in seismic zone and, in particular, characterized the behavior of shear stud walls under horizontal loads. Hence, a contemporary house design is presented to show architectural and environmental possibilities.
