  • Inspection of the technical condition of precast reinforced concrete columns of the ABK building of a cotton mill in the city of Shakhty

    The article discusses the results of a survey of the technical condition of precast reinforced concrete columns of the building of the administrative building of the cotton mill in Shakhty. A calibration calculation for bearing capacity was made taking into account additional loads. Identified extensive damage the main ones are: - destruction of the protective layer of concrete, exposure and corrosive wear up to 10% of the cross section of the working and transverse reinforcement of columns; - cracks in the protective layer of concrete on the surface of the shelves of columns. The technical condition of the building structures of the administrative building for the period of the survey is assessed as unsuitable to the conditions of normal operation (partially operational). A calibration calculation was made and recommendations were developed for restoring the bearing capacity of precast concrete columns.

  • Analytical determination of thermal and radiation deformations of concretes and mortars with low aggregates content

    Experimental verification of the existing method of analytical determination of radiation and thermal deformations of concretes and solutions on the basis of data on deformations of aggregate and cement stone for materials with low content of aggregates is carried out. The test was carried out on samples of solutions with different content of aggregate-sand based on the results of determining the size changes after heating at temperatures from 105 ° C to 400 ° C. It is shown that at the volume content of fillers less than 52% there are differences between the calculated and experimental values of changes in the size of solutions after heating. Moreover, the differences increase with the decrease in the volume content of the filler, with an increase in the heating temperature and the difference between the thermal deformations of the filler and the cement stone. The obtained results allow to correct the results of calculations using the specified existing analytical method for concretes and solutions with a filler content of less than 52%

  • Bioarchitecture-a modern view of underground construction

    The transformation of the natural environment will force humanity to look for a new look at the problems of architecture and urban design. Nowadays, the construction of passive houses is a standard, and green roofs are included in the design of modern cities. Therefore, the urban cluster will gradually transform into sustainable bionic systems that will protect nature and stop further degradation and exploitation of public green spaces.

  • Mathematical modeling of the distributed ledger in the sphere of real estate lease as a network of mass service

    This article presents a mathematical model of the distributed registry as a Queuing network. The main components of this network, as well as their formal representation are considered. The model of the peer-to-peer network is visualized, the vector of the network state is defined, and the restrictions of the state space are defined. After that, the laws of distribution of individual flows and service time were presented. In addition, the design elements of the infinitesimal matrix were determined. Based on the data obtained, a simulation model of this process was produced. For simulation, the Anylogic package was used. The results of simulation were analyzed and the most optimal parameters were selected.

  • Adaptive models of overcoming the risks of the life world of a young family

    The process of overcoming the risks of destruction of the life world by young spouses is studied. Methods of cognitive modeling are used. The theory of adaptive control is chosen as the basic paradigm. This allowed the study to build on the existing theoretical basis of structural analysis of adaptive systems with models in the adaptation circuit.To use the practical experience of cognitive modeling of systems with the inclusion of a person in the adaptation circuit, for example, training models based on a double feedback loop. It is proposed to use the technology of solving problems, based on the experience of past situations, namely, the technology of output based on precedents (Case-Based Reasoning, or CBR). A generalized adaptive model of reducing the risks of destruction of the life world of a young family on the basis of a double CBR – cycle is developed. The model describes the process of self-development of young spouses through continuous training in complex problem situations
