Yaremenko O. Tense - state of strain of the injured domes and vaults

The object - is an affected reinforced concrete beams, reinforced masonry columns, arches, the cupola and close vaults; the purpose - is evolution of scientific positions and techniques by definition of a tense - state of strain of the affected vaults and their elements at short-term and long act of loading; the methods - is deducing of design formulas for elastic stages of work of a material it is carried out by methods of theory of elasticity; checking of physical relationships for masonry and concrete is executed on baseline of full charts; the long warping is accounted for by charts - isochrones; novelty - the problem of definition of a tense - state of strain and a load-carrying capacity of the affected cupola and close vaults and their elements are investigated; the opportunity of the description of charts of a warping of concrete and masonry is confirmed and additional proved by uniform dependencies; the technique of construction of charts - isochrones is offered at the gradual weighting which is taking into account a regime of erection of a construction; boundary lines of saturation are estimated by the armoring of the compressed and stretched working areas of sectional view - techniques and formulas for calculation of the exposed dome-shaped roofs supported with ring girders are specified at an axisymmetric weighting and close vaults in elastic statement; the technique of deformation calculation affected reinforced-concrete and reinforced masonry dome-shaped roofs is developed in view of cracks and a nonlinear warping of materials. Results -there full charts of a warping for masonry, charts for concrete in conditions of a flat stress condition, a chart - isochrone for concrete and masonry are received; deformations and strength reinforced masonry columns at eccentric compression, determination of boundary lines of saturation by the armouring of the compressed and stretched working areas of sectional view are received too; also refinement of design procedures of exposed dome-shaped roofs and closevaults in "elastic" statement; and evolution of a design procedure of the affected dome-shaped roofs in physically nonlinear statement.
