Tuhai T. Method for rigidity сalculating of flat-strained reinforced composite constructions

The object of the research (r.) is the resistance of flat-strained reinforced composite constructions (FRCC) of industrial and civil buildings. The subject of the r. is the rigidity of FRCC in the presence of different types of cracks. Methods of r. It is used experimentally-theoretical method, general methods of SDB mechanics, the theory of reinforced concrete and software "Lira-CAD". Scientific novelty of the results. It is obtained the basic crack's classification of FRCC; the method of determining their rigidity; improved estimated two-element console model; results of experimental and numerical studies. The practical significance: use in the development of DBN В.1.1-12-2014; at calculation of FRCC in the reconstruction project and in the educational process of the NAU.
