Various types of human perception of the urban environment are studied. Based on sociological data, the percentage of people with different perception of space is determined.Research findings: In cognitive urban studies, cognitive-behavioral urban studies are determined. Various models of human perception of the urban environment are studied. Criteria for assessing the urban environment are developed, which identify adaptive and maladaptive elements of urban space. The selected criteria make it possible to predict a positive or negative impact on the development of urban spaces at the initial design stage. A thorough analysis of the territory development allows choosing the most effective of them to provide the formation of the adaptive urban environment affecting the human psyche.Practical implications: Research results can be used in theory and practice of architecture and urban planning and complement training programs for specialists. Formation criteria and principles of the adaptive urban environment can be included in the design of urban spaces at various levels. Research contributes to further actualization of the human-oriented approach in urban studies and can be integrated in the Human Ecology discipline.Originality/value: The paper proposes monitoring of adaptability of urban spaces according to the given criteria. The principles are developed to carry out a new design, reconstruction or renovation of urban areas. The environment created in this way can have a positive impact on the psychological state of a person.","PeriodicalId":45402,"journal":{"name":"Tomsk State University Journal","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72640173","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}

Аn MIM-10 metallographic microscope is used for the metallographic analysis. The infrared spectrophotometer SPECORD M-80 is used for the material identification. Physicochemical tests of fiber are carried out in a certified laboratory \"Khimvolokno\".Research findings: Dispersed reinforcing fiber made of thermoplastic fiber-forming polymers show deformation in compacting the asphalt-concrete mix at impact points of mineral material grains. At the same time, mineral fiber used as a dispersed reinforcement is not subjected to such deformation. The fiber properties are not affected by natural and climatic factors. It is found that natural and climatic factors do not cause the fiber destruction in dispersed reinforcement. The properties of reinforcing fiber slightly change, which allows them to perform a reinforcing function throughout the established service life of asphalt concrete pavements. Indentation of mineral material grains into fiber made of thermoplastic polymers leads to fiber jamming by grains, that prevents them from being pulled out, that, in turn, increases strength and rheological properties of asphalt concrete.Value: The analysis of chemical fiber characteristics is requireв to satisfy the growing interest in dispersed reinforcement of asphalt concrete. The quality of polymer fiber used for reinforcement can be changed under the influence of external factors and affect the quality of road pavements.","PeriodicalId":45402,"journal":{"name":"Tomsk State University Journal","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89956414","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}

This method, using injection methods for soil transformation, has been previously justified by the authors based on field and laboratory research.However, for practical implementation of the proposed method, the key unresolved research tasks are the determination of the calculated depth of the capillary barrier within the roadbed and its optimal thickness.In this regard, the aim of the research is to provide a calculated justification for the boundaries of the capillary barrier made from injected solution to prevent frost heave in the roadbed.The methodological basis of the study includes theoretical research methods such as abstraction, analysis, and synthesis.The article formulates the condition for transitioning from an \"open\" freezing system to a \"closed\" system and proposes criteria for creating a capillary barrier. A solution is obtained to determine the maximum thickness of the capillary barrier, which depends on the properties of its material and the coefficient of moisture conductivity. The solution to the problem of locating the capillary barrier within the structure of the operating roadbed is presented, based on correlating the zone of intensive moisture transfer with the isotherms of temperatures in the freezing massif.","PeriodicalId":45402,"journal":{"name":"Tomsk State University Journal","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90325385","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}

The experimental results of partially concreted composite beams and beams as part of full-size ceilings are studied and analyzed herein. It is shown that the stiffness graph of simple steel-reinforced concrete beams of any shape can be divided into 3 stages: an initial stiffness drop, normal operation, and transition to the limit state with subsequent destruction. The boundaries of these stages are identified for each beam type. The stiffness of the combined cross-section of the partially concreted beam with the rod reinforcement is calculated using well-known formulas from regulatory documents. The element rigidity without rod reinforcement is determined with the decreasing coefficient. Tests of full-size ceilings with partially concreted beams and prefabricated floors confirm the possibility of using standard formulas for the stiffness calculation. However, the width of the compressed concrete flange should be taken into account by less than 3 times than for monolithic slab. The destruction of bending composite structure is accompanied by plastic deformation in flanges of I-beam, destruction of compressed concrete and steel–concrete interaction. However, it does not lead to zeroing of its rigidity. When residual stiffness reaches the ultimate strength state, it is at least 60–70 % of its normative value. This rigidity can be used for the progressive collapse analysis of buildings.","PeriodicalId":45402,"journal":{"name":"Tomsk State University Journal","volume":null,"pages":null},"PeriodicalIF":0.1,"publicationDate":"2023-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86456554","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}
