This paper presents the results of a probabilistic seismic demand analysis performed on a three-dimensional steel-concrete composite structure composed of two different types of lateral resisting systems in the two principal directions: i) a series of a newly conceived moment resisting frame typology composed of high-strength steel circular columns filled with concrete and mild steel beams; ii) a set of ductile reinforced concrete shear walls. The probabilistic analysis relied on the cloud analysis method that entailed the selection of a ground motion scenario representative of the Italian territory sorted according to magnitude and distance from the epicentre. The variation of the ground motion incident angle was also taken into account. Moreover, a comprehensive comparison in terms of fragility curves with a plane two-dimensional model of the moment resisting frame is presented.
