SINGLE-STOREY BUILDING FRAME OF INCREASED RESISTANCE TO PROGRESSIVE COLLAPSE Russian patent published in 2025 - IPC E04B1/30 

FIELD: construction.

SUBSTANCE: invention relates to construction, specifically to large-span single-storey buildings. Increased resistance to progressive collapse single-story building frame includes metal columns, roof trusses and a links system, as well as a coating of ribbed reinforced concrete slabs with concrete-embedded seams, which support transverse ribs are rigidly connected to the roof trusses upper belt; walls from three-layer reinforced concrete panels with concrete-embedded seams, which support transverse ribs are rigidly connected to the columns outer surface; safety bearing cables located between the upper and lower belts along the truss span with deflection along the square parabola and attached by retainers to the supporting and intermediate posts of the truss trusses. Each support post is fixed to the wall panels and reinforced concrete slabs of the coating.

EFFECT: reduced material consumption of the frame under special emergency loads and higher resistance to progressive collapse.
