Abstract The growing focus on sustainability in structural engineering has driven the development of innovative solutions for constructions with reduced environmental impact. Timber is a renewable material with a low carbon footprint, which has become a key element for sustainability. Nowadays, it is used for all timber buildings, as well as in combination with other materials, like concrete, steel and glass, realizing hybrid structures. In this perspectives, hybrid steel-timber structural systems are emerging as promising solution, exploiting the sustainability, lightness and fire resistance of timber together with the strength, stiffness and ductility of steel. This paper briefly explores the potential of hybrid steel-timber framed structural types. Then, starting from an overview of current trends in hybrid steel-timber framed structures, the possible typologies are identified and a preliminary seismic design of selected archetypes is provided, highlighting pros and cons of the solutions investigated in terms of structural weight. 1. Introduction The increasing global emphasis on sustainability and environmental responsibility in the field of structural engineering has significantly accelerated the interest for innovative solutions aimed at minimizing the ecological impact of constructions. In this context, the use of materials with reduced carbon footprints has become a primary objective for the construction field. Among these materials, timber stands out as a renewable, versatile and eco-friendly resource.
