Examples of objects in which similar cantilever floors and their design features are presented. The implementation variant of a cantilever floor with a length of more than 20 m is proposed, where a box-shaped beam is adopted as a core spatial structure. The calculation was performed using the LIRA-CAD calculation complex. The values of moments and cutting forces for consoles with a length from 21 to 39 m are obtained. The main advantages of the proposed constructive solution are highlighted and possible variants of its execution are given.</p>cantilever floorbox-section beamrod systemsreinforced concrete structuresspatial structuresконсольный этажбалка коробчатого сечениястержневые системыжелезобетонные конструкциипространственные конструкции[Shtab-kvartira kompanii GasNatural [Gas Natural Company Headquarters].
