O. V. Romashko-Maistruk Fundamentals of the energy model of reinforced concrete elements and structures deformation
https://doi.org/10.31174/SEND-NT2020-238VIII29-02
Abstract. This article presents a critical analysis of existing models of reinforced concrete elements and structures deformation. The most important requirements to the model which could claim a generalized role are formed. The most important provisions of such a model have been developed. It is based on the deformation-force model of reinforced concrete resistance to force and the hypothesis of invariance in units of volume and potential energy independence of reinforced concrete element deformation from the loading mode. At the same time, this hypothesis is presented as an energy criterion for depletion of reinforced concrete elements bearing strength, which allows to calculate the total and residual resources of these elements during their long operation.
Keywords: reinforced concrete elements, deformation model, state diagram, curvature, energy resource.

https://doi.org/10.31174/SEND-NT2020-238VIII29-03
Abstract. Non-metallic composite reinforcement (NKA) is increasingly used in modern construction, due to its characteristics such as high strength, resistance to chemical and physical corrosion, low weight and low thermal conductivity, it is increasingly replacing steel reinforcement. The wider use of NKA for reinforcing concrete structures is constrained by insufficient knowledge of the features of their work and limited regulatory support. The regulatory documents of different countries of the world were studied to calculate the bearing capacity of inclined sections of conventional single-span concrete beams reinforced with both steel and basalt- plastic reinforcement (BFRP). A comparative analysis of the actual bearing capacity of inclined sections of reinforced concrete beams and basalt-concrete experimental beams with similar structural factors is applied. A comparative analysis of the actual bearing capacity of inclined sections of basalt concrete beams reinforced with BFRP, and its calculated values calculated according to the recommendations of existing design standards of foreign countries, showed their unsatisfactory convergence. Basically, foreign standards underestimate up to several times the real bearing capacity of research beams reinforced with both steel and basalt reinforcement.
Keywords: basalt-plastic and steel reinforcement, bearing capacity, deformability, crack resistance, static and low-cycle loads.

https://doi.org/10.31174/SEND-NT2020-238VIII29-05
Abstract. The article shows and proves that the identical transformation of the second operand of cryptocurrency operations modifies the direct operation and synthesizes the inverse operation to the modified one. Random selection of single-operand operations to convert the second operand of a two-operand operation provides a random modification of crypto-conversion operations. Thus, it was possible to simul- taneously generate models of direct and inverse two-bit two-operand operations of strict stable coding to increase the stability and reliability of streaming encryption.
Keywords: computer cryptography, cryptographic coding; strict stable cryptographic coding; synthesis of operations; variability of cryptoalgorithms.

https://doi.org/10.31174/SEND-NT2020-238VIII29-10
Abstract. The article is devoted to the study of green environmental risk management in the projects of transport enterprises using foresight methodology as an element of strategic management. The features of green risk management introduction in projects of transport enterprises are considered. The necessity of risk management concepts in projects is determined (taking into account current trends in the greening of economic activity of industrial enterprises). The implementation of proactive risk management as a green is proposed. It involves a forecasting of their characteristics and a forming of a strategic program, which provides for the development of measures not only to protect the environment from their impact, but also to prevent their occurrence. There are two main models in green business: incentive models and life cycle models. Incentive models include functional systems for selling or servicing goods, and design, construction, finance, operation, etc. Also incentive models may contain performance-based models that can have environmental effects, implemented as energy saving companies, water conservation companies, material saving companies and chemical management systems. Life cycle models include take-back system, Green Supply Chain (GSC) and industrial symbiosis. A lot of business organizations use different types of green business models and innovations to support the overall green business model. Thus, their green business model innovations intersect and reinforce each other, based on business approaches aimed at the renewable value of materials. Under the Kyoto Protocol, there is a mechanism called the Clean Development Mechanism. A business organization in a developing country has to implement an emission reduction project that aims to achieve the goals of the Kyoto Protocol to promote environmental sustainable development.
Green business management methods are often characterized by the following statements:
1. They include environmental criteria in all main business decisions;
2. They supply environmentally friendly goods or services, whenever possible;
3. Business is clearly concerned about the impact on the environment;
4. Business is committed to the long-term application of environmental criteria in its daily activity. An important aspect is the addition of the «3R» principle in the practice of doing business. The Three R’s – (reduced, reuse, and recycle) principle involves the reduction, reuse and disposal of waste.
Keywords: risks; environmental risks; risk management; project; transport enterprises.

S. S. Gomon Mathematical model for determining the ultimate deformations of solid wood of deciduous and coniferous species
https://doi.org/10.31174/SEND-NT2020-238VIII29-11
Abstract. A detailed analysis of literary sources of foreign and domestic scientists on this topic was conducted. The method of de- termining the ultimate deformations of solid wood of deciduous and coniferous species is presented. It is established that the ultimate deformations of deciduous (birch, alder, ash) and coniferous (larch, pine, spruce) species by compression along the fibers correspond to the deformations at the maximum moment of the bending element of rectangular cross section. A method for establishing the boundary deformations of solid wood using “moment – curvature” diagrams of bending elements of rectangular cross section. A sequence and block-diagram for determining the ultimate compressive deformations of wood along the fibers have been developed. The coefficients of the polynomial W1, W2, W3, W4 for all studied wood species are determined. The “moment-curvature” and “moment-deformation” diagrams for wooden beams of rectangular cross-section are constructed. For the first time, numerical values of limiting deformations of birch, alder, ash, larch, pine, and spruce wood were obtained.
Keywords: solid wood, moment, curvature, ultimate deformations, «moment-curvature» diagram.

https://doi.org/10.31174/SEND-NT2020-238VIII29-12
Abstract. The preparation of a cargo plan for container vessels requires the record of many parameters. The record of restrictions for container vessels is possible when using Boolean models of integer programming. To solve Master Bay Plan problem it is necessary to prepare the input data. The coefficient matrix forming method for the restrictions of the optimization problem under consideration is proposed. A modified Dijkstra’s algorithm is used to reduce inequalities to postfix notation at the first stage. A matrix of coefficients is formed at the second stage. The example of the inequality analysis for the model and the vessel is given, and the result that has been obtained using the proposed method is shown.
Keywords: automated stowage planning, Master Bay Plan problem, Boolean mathematical model, input data preparation, postfix notation.

https://doi.org/10.31174/SEND-NT2020-238VIII29-14
Abstract. This article presents an algorithm that allows to quickly determine the center of gravity of a vessel. When considering maneuvering control issues, the vessel is considered as a point, the mass of which is concentrated at the center of gravity. The origin of coordinates is placed at the point of intersection of the diametric plane and the mid-frame. The error in determining the location is commensurate with the value of the abscissa of the center of gravity, and sometimes much less. Accurate determination of the coordinates of the center of gravity will reduce the error when finding the ship’s position.
Keywords: abscissa of centre of gravity, static moment of displacement of the vessel; ship landing assessment; displacement; maneuverability.
