Sukhanov V. Scientific essentials analysis of the role of structure concrete in the structure organization of building constructions

Object of study - the concrete structure and the structure of public structures as complex dynamic systems; subject - pattern forming active elements in the form of cracks and internal interfaces and evaluation of their role in the structural development and the degradation of structures; methods - analysis of the distribution of their own strain hardening of the material was held on models of structural cells concrete by graph-analytical method and photoelasticity, detecting and fixing the technological and operational cracks performed using special techniques, the distribution of residual strains in small-piece products and designs performed graph-analytical method. Physical and mechanical properties of cement paste, mortar and concrete were determined by standard test methods, their damage was evaluated using the damage ratio. Resistance of the materials at their repeated wetting and drying, freezing and thawing was assessed using coefficients resistance. When testing flexural concrete elements for the assessment methods mechanical methods were used to measure displacements with photofixing schemes cracking and destruction of nature, to control changes in the density of concrete loft products ultrasonic pulse method was used. Statistical analysis of the experimental results was carried out using the apparatus of mathematical experiment planning (development of PATSM department, Odessa State Academy of Civil Engineering and Architecture); results - methods accounting structure and properties of the material in the robot design as an open complex dynamic systems; proposed methods for estimating damage and technological bundle of concrete mixes vertically molded concrete structures with frame-monolithic building; first proposed change geometric characteristics bent elements, allowing them to regulate the distribution of residual strain and increase thereby their properties; introduction - was carried out in 2 - directions, which are based on the representation of the design in the form of an open complex dynamic system, i.e., as a certain integrity that unites the material and design. First direction - including the ideas and methods of system approach, synergies, mechanics and physics of crack development in a number of disciplines of building specialties . Second direction - implementation of technical findings and recommendations in the specific construction projects and materials.
