Annotation: The theme of an urgency of use concrete filled steel tube columns as a part of frameworks of many-storied buildings is considered. As the example, calculation of spatial computer models of the 30-storeyed house, certain dynamic characteristics and level of internal efforts in elements of frameworks taking into account seismic loading are analyzed. Results of the research and computer modeling of the stress-deformed condition concrete filled steel tube columns under the concentrated axial and vertical cyclic loading are presented. The purpose of research is the estimation of strength, plasticity and character of collapse concrete filled steel tube columns, without adhesion between steel and concrete. Considering that efforts of compression are perceived mainly by the concrete core, the distributed loading to a lateral section of a steel mantle isn’t put, on purpose visually to show drive of vertical pressure upon a tube, at the expense of concrete and steel teamwork. Results of probe have shown that in the absence of clutch between elements of the sample, deformation is concentrated in the field of a concrete core, and almost do not move to a steel mantle that essentially influences character of collapse, both a concrete core, and all design as a whole. The modeling data will be coordinated with values hypothetically provided.
Keywords: concrete filled steel tube constructions, three dimensional stress, adhesion, finite element model, seismic response.
