The procedure of fire-resistance calculation for compressed reinforced concrete elements
Authors: Korolchenko Dmitry , Artem’ev Evgenii
Published: December 2020

Fire-resistance calculations adopted in the regulatory system (both in the Russian and in European) are based on calculations of isofields of section heatup of structural elements. Heatup isofields for reinforced concrete elements specified in the regulatory system have been obtained by the concrete section calculation not considering inclusions of reinforcement bars. But it is known that accuracy of the fire-resistance calculation of reinforced concrete elements depends on performance accuracy of a thermotechnical calculation. Having performed this calculation the temperature field distribution by element section and strength characteristics depending on it are determined. Temperature distribution by element section depends on such parameters as heat-absorption capacity and thermal conductivity of section parts, section humidity. Within the work the approach to solving the problem of consideration of the actual temperature field when calculating fire-resistance of reinforced concrete and steel-reinforced concrete elements has been reviewed. Calculations of fire-resistance at temperature fields not considering inclusions of reinforcement bars (concrete section) as well as at temperature fields considering reinforcement bar inclusions have been performed. Additional coefficients introduced in the fire-resistance calculation when using Russian and European methods have been calculated for the reviewed section with 600×600 overall dimensions. According to calculation results the change of section bearing capacity upon the calculation considering thermotechnical characteristics of the reinforcement bars has been observed.

Authors: Sevryugina N , Apatenko A , Revyako S
Published: December 2020

The solution to the problems of assessing the technical condition of special equipment is presented at a multidisciplinary level, as a combination of scientific and technical, practice-oriented research. The purpose of study: development of a digital mechanism for assessing the uncertainty of the state of special equipment systems with real-time monitoring of the intensity of parameter changes, recognition and predictive notification of the probability of risk-failure. It has been established that, in accordance with the theory of probability, there can be only one failure in a unit at a time, even if several damages are diagnosed, and then there is always a single cause. The introduction of the concept of “integrated parameter” supplemented the characteristics of functional and structural multiparameter connections of the state of the unit and made it possible to substantiate the mechanism for recognizing the uncertainty of the state of special equipment systems as a whole. A diagnostic model has been built based on the use of the main provisions of information theory, which represents the unit as a system containing the risk of uncertainty in terms of failure, which is distributed over all structural elements of the unit. An algorithm for recognizing the spatial displacement of uncertainty zones is proposed, the translation of which into a digital format with the introduction of a characteristic criterion will provide a search for a defect (risk-failure). The practical implementation of the risk-failure recognition mechanism is carried out on a simulation model of a change in the state of a technical system using the example of a cardan joint of a technological machine, which is under severe operating conditions during reclamation work. The inclusion in the design of technological machines of a digital module for monitoring the technical condition of the unit is substantiated, including: a module for recognizing the elemental structure; a software shell with a calculation algorithm for evaluating parametric changes; module of interface predictive notification of risk-failure; service control module by state.

The article examines the target attitudes of Russian consumers to the services of “green” hotels. The authors substantiate that among the consumers of hotel services, the so-called millennials are gradually beginning to prevail, inclined to collect impressions focused on the choice of goods and services in the digital space. In Russia, at present, consumers are less demanding of the hotel business in terms of its “green” focus. They perceive the “green” orientation of hotels as a marketing ploy, and not a concern for them and society. It is concluded that society, as a whole, faces the task of ecological education of young people within the framework of the value paradigm of “green” development, which will subsequently lead to trends in the choice and model of consumer behavior similar to those in the rest of the world.

Published: December 2020

Building Energy Modeling (BEM) is a complex and diverse process that allows you to achieve better results even with typical design tasks. By using BEM software, it is possible to provide a non-trivial approach to the development of architectural planning and engineering solutions, often combined with each other, to ensure high quality and effective implementation of results. An excellent example of such a process is the use of BEM technology in conjunction with the design of solar heating systems placed on the facades of the building. This approach makes it possible to take into account and practise various subtleties and aspects that are often inaccessible in traditional (without the use of BEM and BIM technologies) design - accurate accounting of heat intake and losses through individual sections of structures, including heterogeneous ones; temperature distribution to individual elements of structures, directly to structures and buildings as a whole, and much more.

Published: December 2020

Research in recent years has shown that the physical health of the population depends on the food quality. Concentrated tomato products (tomato paste, ketchup, sauces, etc.) can become a source of antioxidants necessary for the human body. The quantity and quality of the obtained canned food directly depends on the biochemical composition of tomato fruits and, first of all, the soluble dry matter. In a field experiment, six tomato samples of domestic and foreign breeding, suitable for one-time harvesting and processing into concentrated tomato products, were studied. As a result of the studies carried out, it was found that the chemical composition of the fruits changes depending on the weather conditions of the tomato growing season. On average, with an increase or decrease in dry matter content in tomato fruits by 1%, the calculated yield changes by 13.1 t / ha, which gives an increase or decrease in the volume of finished products during processing by 2.5 t / ha. When growing the studied tomato varieties suitable for modern cultivation and harvesting technologies in the soil and climatic conditions of the central zone of Krasnodar region, the highest calculated yield of finished products was obtained from the LG-1181 sample and the F1 hybrid No. 8504 Heinz.

Authors: Polyakov V
Published: December 2020

The article touches upon the impact of digitalization processes of economic entities and management bodies of the agricultural production system on the formation of a resource-saving paradigm of its development in the context of ensuring the reproduction of natural resource capital. Based on the position that natural resource capital and, especially, its element as ecosystem services largely form the primary basis for the life of both individuals and the entire human population, the need to find the most effective ways to eliminate the contradiction between the possibility of meeting the constantly increasing needs of modern society and reducing the level of natural capital expenditure, i.e. achieving the decoupling effect, is grounded. One of the key factors contributing to the emergence of conditions for the manifestation of this effect is the active introduction of digital technologies in the activities of agricultural enterprises. In this regard, we consider the development of “Agriculture 4.0” concept (Agriculture 4.0) and its basic directions of implementation are the active introduction of digital technologies (in particular, precision farming), eco-oriented solutions, as well as the use of alternative sources of resources. As an illustration of how digital technologies contribute to changing approaches to the formation of economic organizational and managerial relations that arise in the course of economic activity, we consider the formation of digital (platform) business models for the functioning of agricultural enterprises. It is stated that ensuring the reproduction of natural resource capital in the context of more effective provision of a complex of ecosystem services based on the use of digital technologies and it should involve the formation and use of a set of administrative and economic tools that encourage the introduction of resource-saving technologies and are aimed at reducing the costs of agricultural producers. In this context, we consider the practice of paying farmers so-called “payments for ecosystem services”, which takes place in a number of foreign countries, and identify the most important factors in the development of ecosystem services markets.

PT. Skala Maxima Griya Workshop 1 is a company who produces TV cabinets. Raw materials stored in Workshop 1 warehouse are very piling up to over stock. Forecasting is done using a method that is in accordance with the request pattern. Then the best forecasting method is chosen based on MSE, MAD, SDE, MAPE, ME, and MPE the smallest. Forecasting results are used to create a MPS. The data from the MPS is used to calculate safety stock and make product MRP. The results of MRP products are used to calculate gross requirements, lot sizing, and MRP of raw materials. This research uses lot sizing technique EOQ. After calculating the results obtained that the selected forecasting method is DES with alpha 0.1. The safety stock calculation also shows good results where the safety stock that must be prepared by the company is not too much the majority of value if in the round up is 1. The MRP calculation with lot sizing EOQ also shows a good thing where there is a savings in raw material costs of Rp 10,800,000 .00 or 54.18% after using this method.

Aerodynamics on vehicles plays an important role in increasing the efficient vehicles. Nowadays, research in the field of aerodynamics of four-wheeled vehicles is carried out with the concept of optimization of the geometry shape of the vehicle. Some studies found that the best form in the aerodynamic aspect is the streamlined form, because it has the lowest resistance coefficient value, which is 0.04. Previously, the body of Mobil Irit Tarumanagara designed conventionally in Eco Vehicle concept, using experiments method. The experiments method is very complicated and inefficient, because engineers must draw the designs first, mock- up making, making negative molds, and then mold-casting. Aside from the processes, the aerodynamics performance of Mobil Irit Tarumanagara need to be analyzed. Therefore, this study will analyze the aerodynamics performance of Mobil Irit Tarumanagara using CFD (Computational Fluid Dynamic). CFD simulation will be done on 3D on 3 different body models and 5 speed variations: 1.39 m/s; 2.78 m/s; 4.17 m/s; 5.56 m/s; and 12.5 m/s. The mesh used is in tetrahedral form with a total of 76752 nodes in body no. 1; 55439 nodes in body no. 2; 42551 nodes in body no. 3. The results of the simulation presented by two flow parameters; velocity and pressure which shows the best body model is body 3, because it has the most aerodynamics performance, especially at the front and back of the body. The air velocity at front reaches 9.387 m/s; and vortices at the back flows in 3.271 m/s. This results serve as a reference for development on Mobil Irit Tarumanagara’s body model
