moment assigned to the connectors and the level of seismic input. The results confirmed the feasibility of PreWEC like systems having elements with comparable dimensions to a traditional precast system, particularly in the case of light-weight floors made by composite steel-timber elements. The results of the parametric analyses were further validated through nonlinear static and dynamic analyses considering a planar finite element model for a given case study. The results show the effectiveness of the re-centering behavior but highlight the conservativeness of the considered design procedure. Finally, some preliminary considerations have been obtained from a Life Cycle Assessment in function of 7 impact indicators and 2 resource-use parameters. Herein, only the embodied impact of the materials adopted in the two lateral force resisting systems has been considered. The broadening of the scope of the study to other life cycle stages, such as transport and end of life, is an important focus of further research to provide a valuable and robust tool to support sustainable design choices.
