The paper is devoted to the implementation effectiveness of the regional programs on lowrise housing development. The analysis shows the program inconsistency with the existing instruments of urban planning, land management, accessibility for the population. Such programs are insufficient in regions with specific climatic conditions, for citizens employed in socially significant industries.
This paper shows the problems of low-rise housing in the region, substantiates methodological tools for the development of new regional programs in this field, which, in turn, must meet the requirements of comfortable living conditions in order to solve socioeconomic problems.
In modern urban planning decisions, the conceptual basis is not systematically investigated and developed when determining the development prospects of regional settlement systems. The priority of such decisions is to meet the requirements for spatial planning, urban planning zoning, territory planning. This is not enough to ensure the integrity of settlements and planning principles.
The paper identifies and characterizes the urban planning activities such as the development of territorial systems and quality improvement of living environment. Settlement system development largely depends on both basic regional conditions and readiness of territories to initiate urban planning. These processes have the greatest impact on spatial planning as an element of the strategic planning system.
The proposed theoretical and empirical research methods allow to substantiate the transformation stages of settlement systems and characterize their change, formation principles of urban planning, planning, functioning, life cycle. The improvement of town-planning methodology is proposed. All this contributes to the development of regional settlement systems, which can decrease due to the permanent emergence of new urban planning phenomena and processes.
The paper deals with the university environment in Tomsk and presents the analysis of the current classification of university campuses based on their spatial organization and location in the city. A detailed description is given to the spatial organization of Tomsk universities. The availability of laboratories and the need for universities in dormitories are determined.
The criteria are proposed to determine the degree of autonomy of universities with a view to assess the location of university campuses. Depending on the campus remoteness from university buildings, it is proposed to single out the campuses with a low, medium, and high degree of dispersion. Depending on the location with respect to the city center, it is proposed to divide the campuses into universities locating in the city centre, at its boundaries, and on the periphery.
Based on the proposed classification and the analysis of the university building and campus locations, the types of territorial and spatial structures are determined for university campuses in Tomsk.
It is shown that the campus infrastructure in Tomsk is uneven, some of universities require additional laboratories, buildings, and hostels. According to the city-planning analysis, Tomsk universities have a different degree of dispersion. At the same time, the campus location in Tomsk is characterized by a unique city-planning situation, when 73% of university territories (excluding the Botanical Garden) locate at the boundaries of the historical settlement "City of Tomsk", and buildings is the basis for the historical and cultural heritage of the city centre.
BUILDING AND CONSTRUCTION
Purpose: The temperature and stress effects on the operation of concrete elements made of polymer composites and evaluation of their temperature and stress relaxation.
Design/methodology/approach: Modern approach to bridge structure design and mathematical statistics of the experimental data processing.
Research findings: Temperature relaxation and stress-strain curves are suggested for carbon fiber polymer composites in reinforced concrete elements under constant load.
Practical implications: Initial data for adjusting the formulas of the ultimate limited stress for calculating reinforced concrete structures strengthening with polymer composite materials.
Originality/value: The temperature drop effect must be considered in the operation of polymer composites in bending concrete elements.
Cast-in-place and precast construction must consider a possible fracture of concrete along the reinforced joint. Moreover, the joint quality significantly affects its strength properties. The stress-strain state of the joint can be divided into three classical stages.
It is shown that the stress-strain state of cast-in-place and precast construction under a shear load, is characterized by the linear dependence between the maximum shear stress, vertical compression of the joint, and transverse reinforcement. Since the joint deformation relates to friction and adhesion, the Deryagin binomial law of friction is used to determine the bearing capacity identification of the reinforced joint.
The proposed calculation method implies the ultimate shear stress as an exhaustion criterion for the bearing capacity, which based on the true friction coefficient, compression stress and yield strength in the transverse reinforcement. It is shown that the obtained results are in good agreement with the experimental data.

Purpose: Modification of natural sorbents to improve their sorption properties.
Design: Microwave treatment effect on the properties of peat, reindeer moss, moss and pine sawdust.
Research findings: Short-term microwave treatment has no effect on the moisture and oil absorption by peat and moss. On the contrary, the properties of reindeer moss and sawdust are improved, especially of wood waste, i. e., oil capacity increases by 41 %. The microwave treatment of reindeer moss and pine sawdust provides 11.4 and 17 % increase in the sorption capacity in relation to oil products dissolved in water, respectively. The best effect is observed for pine sawdust irradiation with 600 W microwaves for one minute.
Practical implication: Activated sorbents can be used in purification of wastewater containing petroleum products.
Originality/value: The sorption properties of Arctic natural materials modified with microwaves are studied for the first time.
The paper presents the determination of the roughness coefficient of the minor river channel, since one of the main design parameters depends on the minor stream, required for a substantiation of design decisions. In accordance with the regulatory documents of the Russian Federation, the roughness coefficient is taken according to the visual characteristics of the riverbed.
The purpose of this work is to determine the relationship of the roughness coefficient and dimensionless complexes at different water depths (before and after entering the floodplain).
All calculations are performed according to the results of studying the hydrological conditions of the Chernaya river. The roughness coefficient is determined by the numerical method.
Analysis of the maximum depth allows to obtain its certain value. It is shown that the hydraulic radius increases at a higher depth. When the maximum depth is deeper, this dependence is nonmonotonic, and when water enters the floodplain, the hydraulic radius strongly differs from the average depth of the minor stream. It is found that before entering the floodplain, there is a significant stochastic relationship between the roughness coefficient, Reynolds number and the dimensionless complex. After entering the floodplain, there is a close stochastic relationship between roughness coefficient and the Froude number. When determining the minimum water levels, the exponent of Chezy's velocity factor in the Manning formula cannot be considered a constant value, because this can lead to a great error.
