Published: July 2018

The article presents experimental study results of the deformation state of composite cable space frame structures, including composite steel-concrete structures. Composite cable space frame structures are three-dimensional roof framing of long-span buildings. The designed constructions are a new type of roof framing structures and consist of typical composite steel-concrete modules connected with steel cable elements. The operation of composite cable space frame structures under load is characterised by geometric nonlinearity. The aim of the research is to study the deformation state and changing the geometric shape of experimental structures under the influence of external load. The technique of studying the deformation state of the composite cable space frame structures is based on the principles of digital photogrammetry. At the limit state the composite cable space frame structures change their regular shape. In this case, the central vertical points get the greatest vertical displacements, and the displacement value decreases closer to the supports. It is defined that the investigated construction has demonstrated combined action of all its components during the test, which indicates its effectiveness. The application of the photogrammetry method made possible to determine the moment of reaching the limit state of the composite cable space frame structures concretely.

The first attempts to collect and arrange Ukrainian scientific and technical terminology started since the second half of the nineteenth century. Lviv scientific community by T. H. Shevchenko leads terminology work systematically since the nineties. The aim of the community was to create science in Ukrainian language which foresaw formation of national scientific terminology. Ukrainian scientific and technical terminology developed most intensively in the twenties of the twentieth century. Creation of the Institute of Ukrainian Scientific Language contributed to this process. Its scientists compiled and published more than forty terminological dictionaries in different branches of science and technique. The main task and research topic of Ukrainian terminologists during the thirties-eighties in the twentieth century was ultimate approaching of Ukrainian and other national terminologies to Russian one. In the article the authors pay attention to the fact that nowadays not all branches of science and technique have perfect Ukrainian terminology. Creation and unification of necessary terminology is a primary task for terminologists.

In the article the problem of preservation of monuments of architecture in the modern city is considered. Today, this is one of the main tasks of urban development, which is associated with a change in the filling of the architectural environment of the historical centers of the modern city. The experience in this area is generalized in order to reveal new principles that allow testing on the real material the interaction of structures of different epochs for understanding their reconstruction, preservation and protection. In the field of protection of architectural monuments, there is no necessary legal support, as well as guarantees of investments for maintaining and preserving the historical environment. The research was carried out, first of all, on examples of historical architectural objects of the city of Poltava, where, along with architectural monuments, construction of new buildings takes place, which in most cases do not correspond to the stylistic features of historical buildings and distort the urban historical environment, not taking into account the traditions and practice of building previous centuries.

The basics of the reliability theory of small settlements water supply systems were considered. Methods of the reliability calculation of the supply-distribution complex structures were reviewed: pumping stations, water pipes and branched network. The mathematical reliability model of the water supply technological process to the most distant consumers were constructed according to the water supply selected directions. The real possibility of water supply reliability calculation on an actual example was shown and a graphical representation of the results was performed.
Industrial architecture as a system

It is known that industrial architecture is the important part of modern world. It brings profits and goods to our globalized soсiety. But industrial facilities is the most susceptible to obsolescence because of dynamics of technical progress development and different economic changes in societies.Industrial architecture, as an independent type of an artificial anthropogenic environment, is about 300 years old. Over the entire period of its existence, it has changed many times, depending on the development of technological progress. The evolution of the ideology of industrial buildings on the territory of Ukraine was uneven with certain jerks. This was facilitated by certain socio-political and military historical events, so Ukraine achieved active industrial development in the -1950-70s. During this period appeared the scientific specialization 18.00.03 "Architecture of Buildings and Structures" which was combined with the specialty 18.00.02 "Architecture of buildings and structures" at the end of this period. From 1961 to 1991 the leading research and design center for industrial buildings was the Scientific Research Institute "TsNIIPromzdaniy", which is located in Moscow. This organization set the direction of development of enterprises to the whole Union (and for Ukraine, which was part of the Union). In the late 1980s, this organization carried out the development of new concepts of industrial enterprises under the state order. During this period a number of concepts of mobile and adaptive industrial enterprises were developed. Adaptive enterprises were introduced in the 90s of the 20th century. But this evolutionary change in the policy of development of industrial enterprises was outstripped by the collapse of the territorial organization of the Union.
Thermal Insulation Materials With High-Porous Structure Based on the Soluble Glass and Technogenic Mineral Fillers

The raw material mixture from the silicon-like technogenic component the ash-removal of thermal power plants and the preparation methods of  waterproof porous heat-insulated materials wide usage for raw mass hot foaming powdered two-stage technology are developed. The development uses the polyfunctional properties of liquid glass  as a) the binder component; c) breeder; c) the speed regulator of the clamping mass hardenin. Its optimized version begins to solidify at its usual temperature from the moment its "reproduction" is soluble glass and forms a paste-shaped cake with a set of properties necessary for the next fragmentation. The proposed formulation allows compositions processing in various ways, with the formation of granular heat-insulating fillers, materials for thermal insulation in complex structures, slab and shell-like types of thermal insulation materials. The task is set, depending on the goals and features of the tasks being solved; it is possible to conduct several different methods at the final stages of their obtaining. Two stages of the recycling process determine the character and behavior of the rare-glass composite systems constituent components during heat treatment, their strong adhesion to most structural materials and the need to solve billets easy removal problem from the molding unit. Study results can be used in the field of building materials production, in particular porous artificial products, in obtaining granular insulating material and light aggregate for concrete industrial and civil construction, in thermal engineering as thermal insulation, etc.
