Title of the articleNumerical experiments in researches of spatial work of steel-concrete floorings
Abstract.At research of steel-concrete designs there is a need of their analysis intense the deformed condition at various modes of loading. Different mathematical approaches are used in order to define stress-and strain mode. At the moment many researchers in search of effective model engage application software complexes, that is numerical experiment. However reliability of received data depends heavily on the chosen model of numerical experiment which should correspond to the physical model of structural behavior. Application software complex ANSYS was used for numerical experiment here. For initial data strength and geometrical parameters of experimental large-scale model of composite steel and concrete flooring were taken, testing of which took place at laboratory facilities of Kazan State University of Architecture and Civil Engineering. Experimental constructions as well as the method of full-scale tests are depicted in the paper, and the analysis of test result is carried out. Computer-aided pictures of deflection, stresses in composite steel and concrete construction are shown, stress and strain diagram of steel beam and RC slab for different level of loads is analyzed. Shown the pictures of tension reflecting spatial work of flooring. The comparative analysis of charts of deflections average is shown to a part of flooring in a zone of the steel profile, received by a settlement way according to the ANSYS program and according to tests of large-scale model of flooring at its spatial work.
Keywords.Composite steel and concrete structures, numerical experiments, intense-deformed condition.
