The invention relates to a motor vehicle body structure having at least one structural node, providing resistance to impacts, between at least one first, extruded longitudinal element (2, 4), a second, cast element (3, 5) that is secured to the first element, and a third, hot-stamped element (1), a set of cold-stamped joining and reinforcing brackets (7, 8) interfacing with said first and second elements by connections comprising holes (814, 815, 825, 835, 825'), and by welded connections with said third element, and where relevant interfacing with one another by connections (8183, 8283), in particular by welds, such that said elements are secured to one another, and such that the joint between said first and second elements has inertia with respect to impacts, in particular transverse inertia, and comes to bear against said hot-stamped element in the event of impacts.
