Problem statement. The rapid expansion of the technosphere, unbalanced geopolitical, ecological, and biological processes of modern times demand a complete reassessment, a deep understanding, and the study of risk in all spheres of human life and activity. War and the non-trivial actions of aggressors force us into the necessity of reactive risk management, not excluding the need for proactive risk management. This complicates the determination of the priority of preventive measures at each stage of the activities of subjects and objects of risk, requiring the combination of these principles and the continuous reconsideration of risks to develop effective positive-compensatory measures. The actual state of human (humanity's) protection indicates that without the creation of a “science of risks”, without the establishment of a corresponding academic discipline, further effective and rational risk management is no longer possible. The purpose of the article. Justification for the Introduction of a New Academic Discipline “Safety Riskology” in Engineering and Technical Specialties at Higher Educational Institutions in Ukraine. Conclusions. The conceptual notion of “safety riskology” has been “synthesized” for the first time. The need for teaching a new academic discipline, “Safety Riskology”, in higher education institutions has been justified. During the instruction of this discipline, it is proposed to shape in learners advanced competencies in the identification, analysis, assessment, and compensation (balancing) of risk, considering the types and characteristics of the activities of risk subjects and objects. The demand for professionals with contemporary knowledge in safety riskology is identified across all sectors of the economy. Discussions on the initiation of the independent science of “Safety Riskology” have been initiated.

Problem statement. Improving energy efficiency is a priority for both the European Union and Ukraine, which has a clear and consistent direction of development in accordance with the strategies of the European Green Deal. Residential buildings consume a large percentage of the electricity produced, and improving the energy efficiency of buildings will contribute to energy conservation, as well as energy security and energy independence from energy imports. Significant savings in energy consumption can be achieved through the development and implementation of energy management systems to implement energy-efficient management of modern buildings and the use of smart technologies in buildings, which will allow to control and optimise energy consumption and promote the rational use of energy. The purpose of the article. To develop an energy management system for the residential complex “Panorama” in Dnipro city. The work was carried out within the framework of the international project PRECEPT [1] under HORIZON 2020 programme. Conclusions. An energy management system for a residential complex based on monitoring of climate and air quality parameters is proposed. The system has been successfully put into operation, and in real time receives and processes external data on energy costs, weather conditions and other parameters, analyses and accumulates data, makes the necessary decisions on energy consumption and sends the results to consumers and building managers to save energy or improve comfort.

The assessment of the structures’ technical condition is conducted in accordance with current regulations. During such assessment, various methods are used to determine the physical and mechanical characteristics of the structure’s material. Usually, a single measurement is performed, but in some cases, it is necessary to establish observations to determine the behaviour of the observed defects. Particular attention should be paid to buildings that have not been in use for some time and no measures have been taken to preserve the structures. Since the conditions of concrete formation and hardening in the samples during the establishment of taring dependencies and in the structure in operation are different, the existing non-destructive testing methods do not adequately reflect the properties of the structure’s concrete. Experience in the use of ultrasonic devices and our own research to improve the ultrasonic method allowed us to recommend limiting the scope of this method to periodic inspection, since it is quite easy and accurate to track relative changes in the material of the structure. The purpose of this work – verification of the effectiveness of the improved method of conducting periodic control of concrete properties in the conditions of a real object. Results. The technical condition of the structures of the multi-story building was assessed. Within the scope of the survey, the capabilities of the modernized method of periodic control of the concrete structures’ properties during their operation were checked. Ultrasonic devices are involved in the work, provided that the measurement sites are specially prepared. An increase in the accuracy of determining material properties has been demonstrated. Conclusion. The developed method of periodic control of the concrete structures’ properties demonstrates the low complexity of the work and the sufficient reliability of the obtained results, which allows us to propose it for use in determining the technical condition of the structures in operation.

Problem statement. These days, the main method of monitoring the buildings and structures state is through periodic technical state assessment and monitoring. This is an important practice that guarantees the reliability and safety of the operation of buildings and structures, helping to identify and establish the obvious and possible causes of defects and damages. However, the current practice of storing the results of surveys and monitoring is often limited to records in paper reports, which makes it difficult to analyse over time. Thus, there is a need to create a digital information system designed to record and store the results of monitoring of buildings and structures. This will make the data accessible and organised for specialists, simplifying analysis and ensuring their effective use for decision-making. Such a system will significantly improve the safety and efficiency of buildings and structures management. The purpose of the article is the development of a database architecture for the digitalisation of information related to the inspection and monitoring of the technical state of buildings and structures. Conclusions. The developed database structure will allow storing information about buildings, their owners, location, structures, defects and damage identified during visual and instrumental inspections, as well as organisational and technical measures aimed at bringing structures back to normal technical state or reducing the impact of negative factors. This will contribute to more efficient management and help maintain the property in good working order, reducing the probability of emergency situations.

Formulation of the problem. The stability and safety of buildings and structures directly depend on the technical condition of their structures. To prevent the occurrence of emergency situations, it is necessary to maintain structures in a working condition, which is achieved by assessing their compliance with regulatory and project requirements. Accordingly, the question arises in the consideration of existing monitoring methods and legislative and regulatory documents related to the assessment of the technical condition, which is considered in the context of the monitoring component. The purpose of this work is to study the provisions of laws and regulatory documents related to the monitoring of the technical condition of buildings and structures, review existing monitoring methods and determine the further direction of research to improve monitoring tools. Conclusions. Monitoring and assessment of the technical condition of buildings and structures are an integral part of modern engineering practice, which are prescribed at the legislative level and in regulatory documents of the construction industry. The analysis of monitoring methods showed that there are ready-made solutions for both measuring devices and software for automated continuous monitoring of the technical condition. When performing monitoring based on a periodic assessment of the technical condition, the least developed are the information systems that provide collection, systematization, processing, storage, access, display and distribution of data on the condition of construction structures of buildings and structures in different periods of construction and operation.

Problem statement. Standardized and design parameters of concrete usually differ from the actual values obtained by the concrete of a structure during construction. The use of non-destructive testing devices usually requires their calibration, which is carried out by the vast majority only based on the results of determining the physical and mechanical characteristics of concrete of cubic samples. However, since the conditions of concrete formation and curing in the samples and the structure differ, the existing methods do not adequately reflect the properties of the concrete in the structure. Experience in the use of ultrasonic devices and personal research to improve the ultrasonic method allowed us to recommend limiting the scope of this method to periodic monitoring, since this method can easily and accurately track relative changes in the material of the structure. However, to assess the technical condition of structures, not only relative but also absolute values of the PhMC of the structure material are required. Such data, according to preliminary considerations, can be obtained with proper reliability only by using mechanical methods of non-destructive testing. The purpose of the article is determination of the way to improve the methodology for application of mechanical non-destructive testing methods. Results. The possibility of direct determination of the elastic modulus during the interaction of an indenter with a semi-infinite space with elastic-plastic properties is considered. Four stages of interaction are distinguished, depending on the nature of the forces that provide the indenter's motion, as well as the type and number of system elements involved in the interaction. The equations of conservation of the amount of motion in the system are created and the results of their solution are analyzed. Conclusions. The analysis of the conducted studies shows that it is quite difficult to obtain a solution with the necessary indicators at acceptable costs. At the same time, the reliability of the results obtained is low. To reveal the resulting uncertainty, it is necessary to introduce additional equations into the system, which can be created on the basis of additional measurements. Thus, improvement of the methodology for determining the properties of materials requires modification of the system of equations and additional measurements with subsequent calculations.

Thus, improvement of the methodology for determining the properties of materials requires modification of the system of equations and additional measurements with subsequent calculations.","PeriodicalId":228894,"journal":{"name":"Ukrainian Journal of Civil Engineering and Architecture","volume":"10 13","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140430280","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. From time to time, natural or man-made disasters (floods, fires) occur in various parts of the world, during which residential and infrastructure objects are completely or partially destroyed. Due to the destruction of houses, detached or multi-storey, as a result of hostilities, people are forced to leave their destroyed buildings and look for temporary accommodation. Unfortunately, due to the open military aggression of the Russian Federation that began in February 2014 on the territory of the Republic of Crimea and the Donetsk and Luhansk regions and the second, more intensive phase of military operations from February 2022 on the territory of ten regions of Ukraine (Donetsk, Luhansk, Zaporizhzhia, Kherson, Mykolaiv, Kharkiv, Sumy, Chernihiv, Zhytomyr, Kyiv regions). In the territory of the specified regions, during the hostilities, the housing stock of some cities and villages suffered significant destruction (Mariupol, Irpin, Gostomel, Bucha), in addition, there are a large number of families who are forced migrants fleeing from the temporarily occupied territories. At present, it is important to design a separate residential modular building from the available building materials on the Ukrainian market and in accordance with current building, climatological and sanitary norms of Ukraine. The aim of this work is to design an economical autonomous modular building from publicly available building materials, which will meet state building standards for reliability, energy efficiency and sanitation. Conclusions. A modular building has been designed that meets all the necessary modern reliability criteria. Local public building materials are used for the construction of the building, which significantly reduces the total cost. The construction of the house is made in factory conditions, and the erection is carried out on site within 2 days. The building is designed to be collapsible, which allows it to be moved for repeated use. The cost of a modular house is UAH 146,808. (as of May 2022). The low cost of construction is relevant in the period of weakening of the economic capacities of the state.

Problem statement. The issue of energy efficiency is one of the key problems in the construction industry. Increasing attention to this aspect has led to the development of new technologies and tools to improve the energy efficiency of buildings. One of the powerful software complexes for BIM modeling is Revit. The program has built-in tools for analysis. One such tool is Energy Analysis and the My Insight application in Revit software. This tool allows you to calculate the energy consumption of the building and its energy efficiency. With its help, you can perform an analysis of the building's energy consumption in different seasons and under different operating conditions. To achieve energy efficiency of the building in Revit, you can choose materials and change their thermal characteristics or choose materials that have high energy efficiency and durability, develop new material connection nodes and calculate their heat loss. The use of energy-saving technologies, such as energy-efficient windows, solar panels and others, allows you to take into account the contribution of these technologies to the overall energy consumption of the building using the same Insight application that is relevant today. The purpose of this work is to increase the energy efficiency of the house at the design stage using the ВIM model with the help of the Insight cloud service. Conclusions. Energy efficiency improvements in Revit software and its Insight application help reduce building energy consumption and reduce heating and air conditioning costs. This not only helps save the planet's resources, but also reduces costs for building owners. Using these tools allows you to create energy-efficient and climate-resistant buildings, which is an important task in today's world.
