Published: March 2020

Abstract
The article presents the results of a functional sociological study of the design features of equipment for the educational environment of the university. The analysis of publications and directly university space of interiors testifies to the existence of a certain contradiction between the existing socio-technical environment of the university and the necessary equipment for the developmental education of students – of future designers. The problem arising from this discrepancy is the change in the object content of the medium by filling it with new equipment. The study was conducted by the team of teachers and students who, on the one hand, are active consumers, and on the other hand, they are given the opportunity to implement the most progressive ideas.
Based on the general characteristics of the architectural environment equipment, its typology and the connection of all environmental components, we have chosen different premises of the university. For each of them, a list of equipment was compiled, features were formulated, and only then was the design carried out. One of the main design features that was taken into account when designing equipment was shaping, which not only considered the functional purpose and ergonomic convenience, but also implemented an emotionally-oriented approach. In the course of the functional-sociological research, the main criteria for evaluating equipment for the educational environment of public institutions were selected, the main requirements and design features were determined. In this paper, we have described: a hypothesis, a research model, a goal and objectives, and ways to achieve them, to obtain an effective result. Research methods are based on a comprehensive study of theoretical and design materials to identify the features of equipment design and the content of the educational environment based on the functional-structural methodology. Showing the students’ project proposals on the organization of the educational environment of NMSTU.

Published: March 2020

Abstract
Modern methods of welding high-strength reinforcing steels were analyzed. Comparative studies of welded joints obtained using manual arc welding and welding in a reducing atmosphere of carbon monoxide were carried out. A chemical and metallographic analysis of welded joints was performed. It has been established that welded joints of microalloyed steels made at low temperatures may have reduced strength and viscous properties. The possibility of making welded steel joints using highly-efficient arc welding in a reducing medium of carbon monoxide was investigated. Welding modes have been selected to ensure the formation of a quality welded joint. Studies showed that the use of the proposed welding method in a reducing medium of carbon monoxide ensures full strength of the welded joint and the base metal.

Published: March 2020

Abstract
This article is devoted to the problems of passive solar heating systems application in the modern heat supply systems. During the last decades a Trombe wall is the most popular system among other passive heat supply systems. Solar radiation intensity is the main factor, which has the huge impact on the thermal effectiveness of a Trombe wall. Making a decision regarding Trombe wall application in a heat supply system depends on the correct forecasting of solar radiation intensity on the surface during the heating period. This article contains the brief calculation for forecasting of solar radiation intensity on a Trombe wall surface. The main innovations in the calculation under consideration are taking into account of clouds impact, as well as determination of solar radiation intensity on a horizontal surface, if there are no values for the set city in NASA data bases. The calculation results has showed, that in case of Harbin climatic conditions a Trombe wall can allow to provide 32% of required amount of heat energy in the coldest month. Annual savings of heat energy are approximately 61%. Thus, a Trombe wall, as an additional heat source, is a reasonable option for the heat supply system in the set climatic conditions.

Abstract
One of the most effective types of modern building structures are combined systems sprengel type for cold areas and aggressive environments. Structurally, they consist of a stiffening beam reinforced with one or several pre-stressed flexible elements - ties. The practice of designing such systems has shown that the greatest efforts in a stiffening beam arise under the action of non-equilibrium, including one-sided loads. To solve this problem, a technique based on the use of heuristic optimization methods has been developed: a genetic algorithm and an annealing simulation algorithm.

Published: March 2020

Abstract
According to results of the carried out research, the most significant heat engineering heterogeneous sections of wall enclosing structures of three-dimension block buildings were identified. The use of option with attaching a hinged panel to a threedimensional block with the help of edges along the contour of panel worsens thermal technical mode of the structure. Horizontal junction of wall panels carries the greatest thermal risks and is most responsible when designing a building. Structures of outer wall panels with ribs have practically no potential for energy saving. Fastening a hinged panel to a three-dimension block with the help of dowels equally spaced in the panel plane improves its thermal performance. Compared to the design solution in the proposed option the reduced resistance to heat transfer of outer walls is increased by 31%. High heat insulating effect in this case is achieved by improving design solution of the wall, rather than increasing thickness of insulation layer, which is an economically feasible measure. Designs of outer wall panels with dowel connections are promising from the point of view of thermal protection and can be used for thermal renovation of facade systems in three-dimension block buildings.

Abstract
The paper investigates some design peculiarities of public green spaces used by mobility- and visually–impaired citizens. The subject of studying is a sensory garden as a tool enabling to acquire important knowledge, develop skills, control emotions, and maintain self-confidence by people with special needs. The paper aims at establishing the techniques of creating a sensory garden in a visually-impaired children’s school area based on universal (inclusive) design concepts. To this end, the paper generalizes works on forming a universal design for mobility-impaired population; considers ornamental plant assortments and the effect of introducing ornamental flora in the south of Primorsky Krai (Region); a research project has been done on landscape arranging a visually-impaired school area in the town of Artyom, Primorsky Krai (Region). As a result, a sensory garden universal design has been created which takes into consideration emotional, sensual and physical needs of physically-challenged school students who cannot feel the same as other society members in public places due to their special needs. The proposed project solution may have a positive therapeutic healing effect on school students which results from being in nature and which would allow mobility-impaired children to experience the same senses during their walks as ordinary kids do.

Authors: Kopylov V E , Burenina O N 
Published: March 2020

Abstract
The study of the properties of asphalt concrete modified with activated mineral powders is described. Mineral powders were exposed to physicochemical activation by the joint grinding of limestone with oil sludge in a ball mill in order to produce asphalt concrete samples. Modification of mineral powder grains surface can improve adsorption layer properties. This leads to sharp increase in the adhesion between bitumen and mineral powder grains. Activated mineral powders are characterized by lower porosity, bitumen capacity and swelling. Water resistance of such samples is higher than that of non-activated powders. It has been determined that production of asphalt concrete with activated mineral powders requires 57% less bitumen than production of control samples. At the same time, the physicomechanical properties of asphalt concrete samples fully satisfy the requirements of regulatory documents.

Measuring the Strength of Concrete in the Underwater Part of Hydraulic Structures
Authors: Goncharov A 
Published: March 2020

Abstract
Devices for nondestructive testing of concrete strength (separation with chipping, ultrasound, elastic rebound method) allow to measure the strength only in the air. But for inspecting hydraulic structures (for example, piles of berths), it is necessary to measure the strength of concrete under water. For this purpose, it is possible to use the method of plastic deformation using a shotgun as a percussion device for spearfishing while providing a constant (controlled) force of impact. The works described in the article on obtaining special calibration dependences allowed to successfully apply the method of plastic deformation for measuring the strength of concrete in the inspection of piles of berths in the Black, Barents and Okhotsk seas
On Standard Requirements to Cement for Concrete Used in Marine Environment
Authors: Vavrenyuk S V , Efimenko Yu V , Vavrenyuk V G 
Published: March 2020

Abstract
The article describes the process of leaching (washing-out of calcium hydroxide from the cement stone) the concrete in a zone of variable sea level under the action of capillary forces, resulting to increase the diffusion permeability of concrete against aggressive ions.
It was noted that along with physical factors like the density (permeability) of concrete, the corrosion processes in the marine environment are associated with chemical factors, in particular with the content of tricalcium silicate in clinker which is the main supplier of calcium hydroxide.
In this regard, we researched the current regulatory documents (GOSTs) on cements for the requirements for the maximum content of tricalcium silicate in clinker. The research pointed out the absence of requirements for this indicator there, while many researchers believed that the role of tricalcium silicate was important enough in ensuring the frost and corrosion resistance of concrete in the marine environment in the zone of variable level.
