The notion of a "mixed" structure
Generally speaking, a structure can be defined as mixed if, at the level of most of its elements (beams, columns, connections, slabs), it combines two materials of different natures and properties, in this case steel and concrete, with the aim of making the most of this combination, both in terms of structural operation and construction cost. Mixed-use structures should be distinguished from hybrid structures, sometimes improperly called "mixed" structures, made up of homogeneous elements of different materials, such as a building with a reinforced concrete core on which is supported a framework consisting exclusively of steel beams and columns.
