Opanasenko E. Stress-strained state of steel-concrete frames shells of industrial buildings

The object - frames of shells of industrial buildings; purpose - development of a design procedure of steel-concrete frames shells of industrial buildings on force influences in view features of deformation and optimization of sections; methods -analytical and numerical; dependences for the description it is intense - deformed conditions of steel-concrete frames skeletons at the force influences, based on use of diagrams M-N of carrying ability of steel-concrete elements; numerical realization of the submitted decision is executed; novelty - diagrams M-N of steel-concrete elements rectangular section for various thickness of a holder, classes of concrete, the attitude the sides of section are received; diagrams M-N of steel-concrete elements rectangular section in view of length; parameters of functional connection between geometrical characteristics of steel-concrete sections; use schedules M-N for an estimation of carrying ability steel-concrete frames shells; the design procedure of parameters optimization sections is developed; results - the design procedure tensely-deformed conditions of steel-concrete frames skeletons with rectangular optimum sections is developed by means of schedules M-N; diagrams of carrying ability M-N for steel-concrete elements are received; dependences between geometrical characteristics of sections are received; the sphere of the use - projecting, reconstruction, strengthening.
