Methods of calculation of reinforced concrete monolithic floors with hollow liners

Abstract

Monolithic reinforced concrete slabs overlap with hollow liners have great advantages over traditional solid. Their use can reduce their own weight, reduce the load frame of the building, increase spans, improve heat – and sound conductivity will overlap. However, the implementation of such panels in construction is constrained by the lack of theoretical research and necessary regulatory framework for design. In the article the methods of analytical and numerical modeling in ITU complexes of slab work with hollow liners are examined. It is considered four possible methods of the computerized modelling of the floor slabs of the overlap with cross cavities in combination with full-bodied AREAS OF the plate using SP lira-Cad. The results of the efforts and displacements of the slice plate. It Is shown, that most adequately reflects the tense and deformed condition of the calculation 1 – overlap normalized cooker. This method is the simplest in terms of modeling complex architectural forms of overlap, has satisfactory similarity of results, allows to select necessary reinforcement using Postprocessors. This method is recommended for modelling the spatial work of the building frame, to assess the effort and reinforcement of the necessary slabs, frame elements and foundations.
