Abstract
The paper is devoted to the building architecture in Ancient Greece of Classic and Hellenic periods (V-I ages B.C.), namely urban and country houses and palaces. The town-planning aspects and functional structure of closed-type and peristyle houses are considered as well as façades, architectural elements and details, and building materials used. It is shown that a modest appearance of these houses is in contrast with their interior. Laconicism observed in façade decoration can be explained either by poverty or natural modesty of democratic Greeks and their reluctance to draw attention to their houses.

Abstract
The construction of wooden churches was facilitated by the existence of large wood re-serves, a cheap building material. With the development of Siberian lands, the first wooden churches were built together with the construction of fortresses and prisons. With the spread of Islam in Siberia wooden mosques were also built. Despite the replacement of wooden churches by stone ones late in the 18th century, wooden construction had been developed in towns and villages of the Tomsk province. Moreover, churches which belonged to other religions were built of wood. The paper presents the partial analysis of wooden church architecture late in the 19 and early 20th centuries in West Siberia. Some of design features of Orthodox, Catholic and Muslim wooden churches are discussed in this paper.

Abstract
The paper is devoted to wooden gates of mansion houses in Siberia. Currently, provincial architecture is being intensively investigated and systematized. The absence of a common Russian catalog leads to the exploration of the architectural heritage based on in-depth analysis of some of the regions of Russia. The wooden gate investigations consider them as a small architectural form in defensive architecture and include urban and rural housing of Siberian cities. The analysis is given to historical wooden gates in Tomsk using archival documents and field research. The importance of small architectural forms is shown for the formation of individual historical and cultural image of the city. The paper presents sketches and archival and copyrighted photographs.

Abstract
The paper presents the model of urban typology of central elements of the city which allows identifying and typifying cultural and business complexes, i.e. urban territories not identical to its centre. Classification of the city centers is obtained via qualimetric ranking by the three-level criterion approach, namely: economical and geographic determinants - urban determinants - architectural and town-planning options. These determinants correspond to class - type - sub-type of the city center. The class of cultural and business complex is determined by autonomy, multi-functioning, and predominance of the function of the tertiary sector of economy. The following types of complexes are detected: spot, implicit (resembles Lang’s ‘Edgeless City’), explicit (resembles Garreau’s ‘Edge City’), secondary business centre, satellite city centre, and total centre.

Abstract
The paper focuses on the stress estimation in carbon-reinforced composite longitudinal rebar of normal sections in concrete structures under flexure, tension and compression. As a result of tensile and compression tests the deformation curve is obtained for carbon-reinforced rebar. The dependences are obtained for stresses in steel and carbon reinforced rebar and relative height of compression region of the normal section under static and dynamic loadings.

Abstract
This paper presents the research results on the technical state of bearing structures of the frame and foundations of technological units of gas compressor station. Visual and instrumental inspection and vibration tests of foundations were performed to estimate the technical state of bearing structures. The results indicate to defects and damages in foundations which have a negative impact on their performance. Crack openings 0,1 mm width are detected in foundations; the strength of concrete foundation is below the designed. Amplitude-frequency characteristics obtained during the vibration tests indicate to the excessive horizontal displacements of foundations with respect to the limit values regulated by normative documents.

Abstract
The paper presents the concept of masonry protection using a coating material consisting of adhesive anti-efflorescence and finishing hydrophobic biocide layers. Theproposed bond plaster is based on Portland cement which represents the adhesive anti-efflorescence layer. The mortar based on this mixture absorbs 9,62 wt. % of 5 % salt solution when applied to brick and during setting. After drying, the adhesion between finishing layer and brick retains in the absence of salt efflorescence on the surface.

Abstract
Non-Markovian processes occur in nature in the form of the structural organization laws of space-time objects at different scale levels. Non-Markovian processes preserve the memory of the past state of the system and its further evolution is largely predetermined by information about previous stages of development. This is typical for solid-phase processes, ceramics, metals and alloys, water and aqueous solutions, and other inorganic objects. Non-Markovian process indicators are harmonious integers of nature, Fibonacci numbers and the golden proportion. The paper presents evidence of non-Markovian process occurred in cement systems. It is shown that during the formation of fine crystalline structure the cement system is capable to produce such elements and generate a low-frequency current, which simulates the intensity and duration of the processes. It is shown that the active phase of self-organization in cement systems is of temporary nature as the energy from outside sources is limited.

Abstract
The paper presents the analysis silicate melt production using the low-temperature plasma. The materials with different content of silicon oxide are selected for silicate melt production due to their content in the chemical composition of silica ranging from 50 to 100 % and relevance for practical use. The chemical composition of silicate melt is determined in the paper. The melting time is calculated for quartz particles under the conditions of low-temperature plasma. It is shown that at 0,65 l/s bulk speed of plasma flow the particles having 1,28 mm size completely melt. Also, it is found that at 1,4 l/s bulk speed of plasma flow the particles with 0,88 mm size completely melt before they reach the bottom of plasma generator, while larger particles melt partially.

Abstract
The paper presents the analysis of experimental and theoretical research which shows that metallic binding between the materials obtained by welding occurs due to chemical bonds between atoms, namely: ion, covalent, metallic. Their formation process is similar to topochemical reactions, and successively flows into the four main physicochemical stages which include the formation of physical contact; atom activation of binding surfaces; collectivization of valence electrons; their three-dimensional interaction at the contacting boundary.

Abstract
The paper presents the research results on the effect of calcium carbonate-based additives on mechanical properties of autoclave-cured foam concrete. Sodium chloride residuals are mineral additive mostly comprising nanoparticles 10-60 μm in size. It is shown that the introduction of calcium carbonate sludge into the concrete mix in the amount of 5-15 % has no effect on the strength properties of concrete. Calcium carbonate additives promote the formation of a porous structure and increase the strength of the concrete samples. The experimental results show that calcium carbonate-based additives in the mixture allow producing samples with D500 and D600 density.

Abstract
This paper presents research of stress-strain state of exterior wall masonry fragments under static loading. The exterior walls of a residential building are made of two layers, namely lining ceramic brick and hollow tile. As a result of experiments the properties of masonry are determined using two methods: testing of ceramic brick, hollow tile, and masonry mortar (according to the standard literature) and testing of masonry fragments of exterior walls. A comparative analysis of obtained results allow estimating the masonry strength under compression and detect the safety factor of exterior walls of the building.
