Problem statement. The patented useful model for the design of the combined raft-pile foundation (CRPF), consisting of a raft part and piles, with a gap of height Δ is made between the raft part and the piles. That is, the distribution of settlements (resistances) of the soil base under the raft and then under the piles (after the hinged connection of the piles with the raft) is assumed, based on the condition of not exceeding the maximum allowable settlement su of the building or structure. The initial settlement of the piles, which arises from the effect of the additional loading (negative) friction force acting on their lateral surface within the compressible layer during the pressure loading of the soil base raft part, must additionally be taken into account to correct the value of the gap Δ. The purpose of the article is to conduct field investigation of the piles initial settlements under the action of additional loading (negative) friction forces acting along their lateral surface in a large-scale combined raft-pile foundation to identify new dependencies and generalize them. Conclusions. On the basis of field studies, a qualitatively new dependence of the pile deformation on the action of additional ground friction forces has been revealed, which shows the "pile up-slip effect" due to the excess of resistance forces on its lateral surface with manifestation of inverse (elastic) deformations of the ground base of the pile. On the basis of field investigation, a qualitatively new dependence of the pile deformation on the effect of soil additional loading (negative) friction forces was revealed, which shows the “effect of the pile slipping upwards” due to exceeding the negative friction forces the resistance forces on its lateral surface with the manifestation of reverse (elastic) deformations of the pile soil base, which indicates the need to take this phenomenon into account when determining the gap between the raft part and the piles in projects of similar CRPF.

Problem statement. Heat supply systems are one of the essential systems for life support. Heat production and consumption require a rational approach, which implies fulfilling the demand with minimal use of resources. In that case, the science-technical and practical demand for increasing the energy efficiency of the country's heat supply systems for the economy is evident, especially in post-war restoration. Ukrainian systems of heat supply have multiple unique features and issues, meaning solving this demand will require the analysis of the actual state of the country's heat supply system. The purpose of the article − to collect and analyze the info regarding the existing heat supply system issues, as well as detect the most crucial issues for increasing the systems’ energy efficiency and further research for optimal solutions. Conclusions. The general problem with the current stage of heat supply system development in Ukraine is defined, as well as the requirement for optimal use of centralized systems and smart decentralization of the heat supply. The relevance of such a formulation not only for Ukraine is confirmed by information analysis on the directions of development of heating systems in other countries. The relevance of this definition (not just for Ukraine) is proven by informational analysis regarding vectors of other countries' heat supply systems development. The complex block scheme of existing heat supply systems issues is provided. It can be used to provide a systematic approach to solving these issues, which will positively influence its efficiency. The collected analysis results are recommended for defining the research vectors and ways to improve the heat supply systems to increase their efficiency.

Problem statement. The purpose of introducing the Methodology for forecasting the consequences of hazardous chemicals spills (releases) during accidents at chemical hazardous facilities (CNO) and transport (hereinafter − the Methodology), was to eliminate discrepancies between the provisions of the Civil Protection Code and the then existing methodology. Therefore, it is relevant to establish the procedure for assessing the chemical situation by forecasting the scale of pollution in case of accidents with spill (release) of hazardous chemical substances (HCS) from technological containers at chemically hazardous facilities, road, river, rail and pipeline transport in accordance with the clause 18 of the Article 17 second part and clause 9 of the Article 35 first part of the Civil Protection Code of Ukraine. The purpose of the article. Study and analysis of the Methodology for its compliance with the set goal of practical use as intended. Conclusions. The implementation of the Methodology came at a time of pandemic quarantine (COVID-19), which was further complicated by martial law. Given that the Methodology has not become a component of the practical work for business entities and the topic of analysis and assessment in scientific circles, we suggest that the Ministry of Internal Affairs suspend its operation and announce a thorough discussion with the involvement of practitioners, scientists and all interested parties in solving chemical safety issues in Ukraine. The authors of the article carried out a detailed analysis with the provision of proposals and recommendations to eliminate discrepancies, overlays, contradictory statements of the Methodology. In the context of improving the material wording, the terms of the Methodology are explained. It is noted that it is advisable to use the Methodology that would correspond to the following principles: ease of use; efficiency of determining the main parameters; efficiency and relative accuracy of the forecast.

Therefore, it is relevant to establish the procedure for assessing the chemical situation by forecasting the scale of pollution in case of accidents with spill (release) of hazardous chemical substances (HCS) from technological containers at chemically hazardous facilities, road, river, rail and pipeline transport in accordance with the clause 18 of the Article 17 second part and clause 9 of the Article 35 first part of the Civil Protection Code of Ukraine. The purpose of the article. Study and analysis of the Methodology for its compliance with the set goal of practical use as intended. Conclusions. The implementation of the Methodology came at a time of pandemic quarantine (COVID-19), which was further complicated by martial law. Given that the Methodology has not become a component of the practical work for business entities and the topic of analysis and assessment in scientific circles, we suggest that the Ministry of Internal Affairs suspend its operation and announce a thorough discussion with the involvement of practitioners, scientists and all interested parties in solving chemical safety issues in Ukraine. The authors of the article carried out a detailed analysis with the provision of proposals and recommendations to eliminate discrepancies, overlays, contradictory statements of the Methodology. In the context of improving the material wording, the terms of the Methodology are explained. It is noted that it is advisable to use the Methodology that would correspond to the following principles: ease of use; efficiency of determining the main parameters; efficiency and relative accuracy of the forecast.","PeriodicalId":228894,"journal":{"name":"Ukrainian Journal of Civil Engineering and Architecture","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130754200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Problem statement. The neighboring country's full-scale military aggression against Ukraine has created many humanitarian problems of a catastrophic nature in our country. Of course, such problems arise in any armed conflict involving the occupation of inhabited territories. One of the extreme measures for the protection of the population provided by the legislation is its evacuation from the combat zone. Unfortunately, this measure is now fully implemented in our country. Today, more than 7 million citizens of Ukraine are forced to leave their homes and leave their region of residence. One of the phases of organizing the evacuation of people is primary temporary resettlement and provision of psychological assistance. Taking into account the climatic conditions of Ukraine, a suitable living environment must be used for primary resettlement. The purpose of the article − assessment of the possibility of public buildings space using for temporary accommodation of evacuated people with the creation of relative psychological comfort. Conclusions. One of the key human needs that significantly affects the psychological state is the availability of living conditions. In order to reduce the stress load, during the development of primary accommodation measures, it is necessary to provide for the living of such groups in a separate space. The concept of primary accommodation for evacuees in partitioned compartments using the living space of public buildings is a compromise, but it has two advantages: the use of existing heated rooms with the necessary utilities and the possibility of all-season accommodation and the creation of conditions to reduce the stress on the individual by separating the people closest to them. The concept of public buildings space using for the quick temporary accommodation of a large number of people according to the hub principle is based on the need to take into account climatic conditions and the use of housing with heating and appropriate communications and the possibility of (relatively cheap and fast) installation of partition structures in them that form a separate living space of the “compartment” type.

The widespread use of polymeric materials in various industries and fields of activity is explained by the thermal stability of polymers, their high strength characteristics, and the durability and reliability of synthetic materials. The introduction of additives can change the physical-mechanical, thermophysical, optical, electrical, frictional and other performance characteristics of the original (base) polymer. The purpose of the article is to investigate the safety of using isophthalic acid filler in a polymer composition. Methodology. Application of theoretical research methods, regulatory documents. Results. The spheres of polymeric materials application are considered. Ways of creating polymers with specified properties by introducing fillers into their composition, which change not only the operational characteristics, but also the physical and chemical characteristics of the original polymer are investigated. In view of the identification for danger of using isophthalic acid as a filler for phenylone, its physicochemical composition, stability, reactivity, toxicity, and environmental impact are studied. The measures and means of ensuring fire and explosion safety, means of controlling hazardous exposure, precautionary measures for personnel and personal protective equipment when working with isophthalic acid are considered. As a result of the research, it is possible to obtain an optimal polymer composition with improved plastic characteristics and safe properties. Scientific novelty. The possibility of obtaining an optimal polymer composition is shown: with improved plastic characteristics due to the addition of the biodegradable isophthalic acid filler fenilon to the polymer material; safe properties for humans and the environment, namely the absence of toxic substances release under the influence of heat, light and other external actions. Practical value. The resulting polycomposite material with updated plastic characteristics and safety properties can be used for further processing of secondary polymer raw materials.
