The change in approaches to the organization of parking space in the conditions of modern urban development of cities is considered. The domestic and foreign practice of designing parking lots oriented to residential development is analyzed. The trend of changes in the design, construction and organization of parking lots in highly developed cities has been revealed, in the direction of moving away from meeting the needs of all car owners in parking spaces to integrating parking spaces into the residential and transport infrastructure of cities. Modern parking lots are adaptive, integrated, functionally changing urban spaces over time, which allow regulating the number of cars on city streets. In Ukraine, the design of parking lots still gravitates towards the level of car mobility and the radius of accessibility to parking lots. The article examines the types, distribution, types by purpose and placement of parking spaces in the city of Vinnytsia. The problem of parking space organization in the city of Vinnytsia has been determined. The peculiarities of the formation of the existing parking space in the city of Vinnytsia, depending on the formation of the existing development of the city districts, functional purpose and the way of using the territory, were studied. The main typology of the city's parking lots and their condition have been determined. The main trends in the organization of parking space in the city of Vinnytsia are presented and rational directions for its further development are proposed, which allow to reduce the use of personal vehicles when moving around the city and free the city spaces from excessive overloading with cars.

The article deals with issues of resistance to cracking at low temperature, low-temperature characteristics of asphalt concrete, tensile strength in bending, and the ratio of tensile strength to bending deformation, which reflects the flexibility of asphalt concrete. When the temperature is relatively low, the asphalt concrete should have a certain deformation capacity, and the temperature shrinkage crack can be reduced under the low temperature condition. The ultimate flexure tensile strain at low temperature is closely related to the performance of asphalt. Increasing the viscosity of asphalt can improve the low-temperature crack resistance of pavement.

The article deals with the relevance of the renovation of children's camps, the development of new approaches to design and their modernization, which is related to the moral and physical wear and tear of existing children's recreation camps. The main tasks for recreation and use of the territories of children's camps are defined. Today, children's camps quite often undergo renovation, which is caused by the non-compliance of the existing buildings and structures of the camp territory with modern standards and requirements. Renovation is a modern alternative to demolishing buildings and building new ones. It allows you to save time and material costs and allows you to adapt existing buildings to modern needs. In the article, the general vectors of recreation development are formed, which are aimed at solving tasks related to the review of the planning, functional and temporary use of the territory of recreation camps. The main ones are: multi-functionality, barrier-free environment, social communicability, self-scaling, architectural and artistic design, beautification of the territory, environmental friendliness, implementation of partnership development, and year-round. Examples of the combination of development vectors in the renovation of children's camps are also given, which show that the camp can be modern, multifunctional, ecological and interesting.

The aggravation of the economic and environmental situation in Ukraine necessitates the development of new efficient technologies for the processing and use of industrial technogenic waste from the thermal power and chemical industries. Such technologies should ensure the maximum degree of use in the production of high-quality efficient building products. The choice of technology for the preparation, processing and use of industrial waste depends on the chemical, mineralogical, granulometric composition and method of production. Despite the fact that such wastes are used mainly as inert fillers, their overall use remains low. The share of their use in the manufacture of building products is 5-12%, at the same time, the manufacture of building products requires additional energy costs. Many industrial and municipal wastes, which are of great practical interest, remain insufficiently demanded for various reasons. In this regard, the popularization of the likely directions for the introduction of industrial waste and the effect achieved in this case is of fundamental importance. One of the main industries for the integrated use of waste is the industry of building materials, where this raw material can act as the basis for the creation of new highly efficient materials. Predicting the properties of such materials is a rather difficult task, the solution of which can be achieved through the formation of a systematic approach to determining quality indicators, as well as predicting and regulating the properties of materials depending on the goals and objectives solved by builders and technologists in the manufacture of building products.

It is shown that the use of solid biomass as a renewable energy source is relevant for the production of thermal energy and electrical energy. but the burning of biomass is accompanied by the release of a significant amount of ash into the environment. The need to organize the primary cleaning of waste gases of heat generators in cyclone dust collectors has been established. The stages of solving problems of aerodynamics and heat transfer in the SolidWorks Flow Simulation CFD package are described. The nature of the distribution of pressures, velocities of gas and solid particles in cyclone filters, the values of heat transfer coefficients in the flow area, based on which the studies of cyclone efficiency, hydraulic resistance, power of the heat exchanger-utilizer and the temperature of heated water were performed. It was established that an increase in the temperature of the inlet gas stream reduces the efficiency of the cyclone in cleaning highly dispersed ash, the presence of a heat exchange surface increases the resistance of the cyclone, but improves its efficiency in capturing solid particles up to 10 μm in size. The obtained results make it possible to improve the design, reduce the metal content, and find rational modes of operation of cyclones in operating conditions.

In accordance with the socio-economic processes that preceded the reconsideration of urban spaces associated with the formation of a post-industrial society, destructive non-functional areas were formed in the structure of modern cities. The loss of primary production function by industrial enterprises has led to a significant deterioration of the architectural and urban planning, ecological and social situation in our cities in general. Therefore, the renovation problem of industrial territories has become an thorny issue, in particular, the identification of ways to harmonize these territories by rethinking and updating industrial buildings. The term renovation refers to the adaptive use of buildings, structures, facilities and changes in their functional purpose. The subject is the hotel function in industrial buildings, realized as a result of the change of the original purpose of the building, like a sign of continuity and functional diversity. The article pays attention to both the favorable conditions and positive consequences of the operation of hotels in industrial buildings, as well as the negative aspects and threats that arise in connection with the use of industrial areas in general. The city of Vinnytsia has great potential for renovation measures of industrial facilities, which today has in its structure a significant amount of the territory of former enterprises that have lost their original function. One of these places is the former factory of tractor units on the street Batozkiy. Therefore, the issue of responsive use and refunctionalization, in particular to the hotel, of former industrial buildings is a priority.

The substantiation of the need to develop and implement new resource-saving technologies for the production of construction mixtures using aggregates obtained as a result of complex processing of solid inorganic construction waste is provided. Analytical studies of technogenic waste processing technologies for obtaining building materials have been conducted. The results of the study of the experience of construction scrap processing are presented, with confirmation of the expediency of the fact that the technology of recycling accumulated construction scrap dumps in the territory where the destroyed buildings were located does not require any new specialized measures. The projected volumes of building materials in the composition of residential construction objects with various quantitative parameters of the constituent components of the elements of the fencing structures are presented. Analytical studies have established that the accumulated volumes of construction scrap from the destruction of elements of buildings and structures in the vast majority include the remains of concrete, reinforced concrete, expanded clay concrete, brickwork made of ceramic and silicate products. Experimental series of aggregate samples were made using experimental samples of construction scrap, their granulometric characteristics were determined and physical parameters were investigated. With the use of regulatory and technical literature, the predicted prescription parameters of the concrete mixture using a new variety of aggregates obtained by re-processing of construction scrap were compiled. The presence of reactive substances on the surface of the obtained aggregates was substantiated and the presence of increased physical and mechanical characteristics of the samples with a decrease in the binder content was confirmed. Recipe and technological parameters for the production of wall building materials using the obtained multicomponent building mixtures are proposed. The results of tests of physical and mechanical characteristics of test samples of concrete using aggregates from solid inorganic waste are presented.

In the work, on the basis of physical modeling on small-scale models, the joint operation of piles and a low grid as part of a pile foundation was investigated and analyzed. The operation of a grid without piles and a grid with different numbers of piles of two standard sizes was considered separately. The force in the piles of the bush was monitored using tensometric equipment. The nature of changes in the share of the grid and realization of the load-bearing capacity of piles in the foundation with changes in their number and length in the group with constant dimensions of the grid were considered. The possible load-bearing capacity of the bush was analyzed according to two theoretical hypotheses: as the sum of the load-bearing capacities of single piles without taking into account the grid plate and as the sum of the load-bearing capacities of single piles and the load-bearing capacity of the grid plate as a foundation for shallow laying without piles. Failure to take into account the work of the grid as part of the foundation gives underestimated values of the loads on the bush, and taking into account the work of the grid without adjusting for the redistribution of forces between the elements of the bush during pile placement leads to an overestimation of the load-bearing capacity of the bush. When evaluating the bearing capacity of a bush through the bearing capacity of its individual elements, it is necessary to proceed from the degree of realization of these bearing capacities in the composition of the bush. The efficiency of using short piles compared to long piles was evaluated.

Failure to take into account the work of the grid as part of the foundation gives underestimated values of the loads on the bush, and taking into account the work of the grid without adjusting for the redistribution of forces between the elements of the bush during pile placement leads to an overestimation of the load-bearing capacity of the bush. When evaluating the bearing capacity of a bush through the bearing capacity of its individual elements, it is necessary to proceed from the degree of realization of these bearing capacities in the composition of the bush. \u0000The efficiency of using short piles compared to long piles was evaluated.","PeriodicalId":221366,"journal":{"name":"Modern technology, materials and design in construction","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133356036","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}
