Item type:Item, Моніторинг технічного стану конструкцій надрукованих за допомогою 3D принтеру(Національний університет міського господарства ім. О. М. Бекетова, м. Харків, 2025) Богаченко, Сергій Вікторович; Титюк, Анатолій Олександрович; Радкевич, Анатолій Валентинович; Савицький, Олександр Миколайович; Смирнов, Антон СергійовичUKR: У статті розглядаються сучасні підходи до моніторингу технічного стану будівель та споруд, споруджених із застосуванням технології 3D-друку. Особлива увага приділяється концептуальним підходам впровадження систем моніторингу на основі Інтернету речей, що дозволяє здійснювати постійний збір даних як на етапі нового будівництва, так і під час експлуатації об’єктів. Такий підхід надає можливість оперативно виявляти дефекти та пошкодження, контролювати відповідність фактичних параметрів проєктним вимогам та прогнозувати терміни безпечної експлуатації конструкцій. Розглянуті концепції також передбачають трансформацію будівельної інформаційної моделі в цифровий двійник, що в свою чергу дозволяє візуалізувати технічний стан, моделювати поширення дефектів, проводити віртуальні випробування та оцінювати ефективність ремонту. Запропоновані підходи створюють основу для інтелектуального управління сучасним будівництвом.Item type:Item, Standards-Based Approaches of Ukraine and India to the Determination of Wind Loads(Publishing House “Akademperiodyka”, 2026) Bannikov, Dmytro O.; Nikiforova, Nataliya A.; Kosiachevska, Svitlana M.; Muntian, Antonina O.ENG: Introduction. The calculation of wind load on building structures is an indispensable component of modern building design, therefore, analyzing the experience of different countries of the world in this aspect is an important and relevant task. Problem Statement. The main difficulty in taking wind load into account during design is the diversity of principles and approaches to its definition, which is based on national ideas and value system in different countries of the world. Purpose. Comparison of applicable regulatory approaches to determining wind loads in Ukraine and India using the example of a low-rise industrial building with an analysis of the system of influencing factors and the degree of their consideration. Materials and Methods. The research was conducted based on an analysis of the approaches of the applicable Ukrainian and Indian standards for determining wind loads. A low-rise industrial building of rectangular shape in plan with a gable roof was taken as the object of the study. Results. It has been established that the applicable standards of Ukraine and India use a fundamentally similar model of wind load, which is supplemented by a system of correction factors to take into account local operating conditions. However, the Indian standard takes into account 12 factors of local conditions against 10 factors in the Ukrainian standard. The methodology for taking them into account differs qualitatively in these standards. At the same time, the value of the aerodynamic coefficient has a quantitative level of correlation within 50 % according to the standards of both countries. For a low-rise industrial building with a gable roof, the fi nally determined level of wind load according to the standards of Ukraine and India diff ers by the amount for side facades — up to 25 %, for end facades — up to 40 %, for the roof — up to 30 %. Th e height wind profi le for the Indian standard is fl atter and has a quantitative correlation level within 50 % for heights up to 20 m above the ground. Conclusions. Th e obtained results provide an opportunity to analyze the applicable national standards of Ukraine and should be used for their improvement.Item type:Item, Step-by-Step Analysis of the Condition of the Side Tunnel for a Pylon-Type Metro Station under Construction NATM(IOP Publishing Ltd, 2026) Radkevych, Anatolii V.; Kuprii, Volodymyr; Dubinchyk, Olha I.; Mazorchuk, Volodymyr F.ENG: This scientific research provides a step-by-step analysis of the condition of the side tunnel for a pylon-type metro station with combined lining. An analysis of the algorithm for applying the New Austrian Tunneling Method to the construction of underground structures in hard rocks (as in the Dnipro Metro) has been conducted. It is justified that the analysis of the stress-strain state in the combined lining for the side tunnel of a station should be carried out in accordance with the stages of opening the working and installing the combined lining. A finite element model has been developed to represent the stages of side tunnel construction. This model also reflects the station structure’s conditions, its dimensions, and the interaction between the combined lining and the surrounding rock massif. The dependences of horizontal stresses in the rock massif and the bending moment in the combined lining on the stage of construction of the side tunnel have been obtained. The conclusion from the step-by-step analysis in the construction of the side tunnel for a pylon-type metro station, built using the New Austrian Tunneling Method, is that maximum stresses and force factors occur during construction rather than during the operational phase.
