Lugchenko O. Rational hollow concrete and reinforced concrete structures

The principles of parameters rationalization of structures with simple outside and complex inside geometry have been worked out. The character of strength distribution of deformation potential energy has been investigated with the aim of using as the criterion of a structure work positivity. Final elements models have been worked out as the basis for the formation techniques of structures with simple outside and complex inside geometry. The influence of different factors on the geometry of concrete and reinforced concrete structures has been studied. The methods of complex structure formation and the succession of production of efficient concrete and reinforced concrete elements with simple outside and complex inside geometry have been elaborated. Using the method of adapting evolution rationalization tasks of cantilever and continuous beams, unbruced beams and a basement wall block have been considered. Experimental research and evaluation of worked out theoretic models adequacy has been made by qualified testing unbraced beams and basement wall block elements. Mechanic devices have been used for measuring. The analysis of the data obtained resulted in elaborating the methods of a structure complex formation and the succession of producing efficient concrete and reinforced concrete elements with simple outside and complex inside geometry.
