FIELD: construction.
SUBSTANCE: invention relates to construction, namely, to composite beams working in bending, used as buildings load-bearing elements. Steel-reinforced concrete beam is made of two shaped thin-walled steel shells, forming upper and lower belts filled with reinforced concrete and flat wall, with die-fixed ribs interconnected by bends of die-fixed studs ends. To ensure upper belt constant size die-fixed studs with bends are engaged with mesh reinforcement.
EFFECT: technical result of invention consists in improvement of beam carrying capacity.
