The analysis of the results of the examination of the technical condition of buildings and structures of enterprises in the sphere of public utilities has been carried out. The basic principles and methods of functional and technological renovation of architectural objects are revealed, accompanied by the transformation of the architectural space and planning schemes of industrial buildings and structures. A number of architectural and structural studies have been carried out in the direction of finding optimal technical solutions for repair, restoration of operational ability and reconstruction of industrial architecture objects in the field of public services for the purpose of their renovation. Technical reports based on the results of technical condition survey of building constructions of buildings and structures exploited for a long time, especially if there were long breaks in exploitation and maintenance, should include a section “Activities to renovate the object”. There is a need to adjust the regulatory framework for design and construction in order to speed up the process of “survey – renovation project – construction of the object”, as well as to restore and improve the base of the construction industry for the implementation of renovation projects. Complicating factors in the process of developing renovation projects of buildings and structures are the lack of design documentation for most facilities, lack of quality certificates for building structures and materials of buildings and structures, the long process from technical inspection to implementation of working design documentation, lack of interest of city authorities in development and renovation of service facilities.

The article discusses the main reasons for the physical wear and tear of metal crane beams of industrial buildings at hazardous production facilities. The analysis of the existing methods for determining the physical wear and the residual life of various structures, as well as regulatory and technical documentation, regulating the issue of conducting inspections of structures and the appointment of the technical condition of structures is carried out. The analysis of characteristic defects and damages of welded crane beams and an analysis of their influence on the bearing capacity is made. The dependence of the amount of physical wear and tear on the duration of operation of crane girders has been investigated. A method is proposed for determining the physical wear and tear of individual structures on the basis of their effect on the bearing capacity of the structure and their operational characteristics, based on the existing methods for determining the physical wear of structures of non-industrial buildings. A method is proposed for determining the residual life of metal structures by the Poisson method, depending on the degree of physical wear and the duration of operation. The use of this technique provides more accurately approach the determination of the residual life of building structures when conducting an industrial safety examination. Based on these data, it is more reasonable to approach the reconstruction, strengthening or overhaul of existing structures, as well as their complete or partial replacement.

The paper proposes an approach to determining the increase of the normative lifetime of building structures on the basis of the algorithm of numerical calculation of the residual life of structures, which is performed on the basis of the results of defining parameters obtained during the technical examination and evaluation of defects, failures and structural damage. To calculate the structures, the simulation of the stressstrain state of the building structures with the involvement of OK LIRA was used. Simulation allowed performing optimization of technical solutions and strengthening of structures for buildings. The methodology is used to design elements for strengthening the structures of buildings and structures. Reliable estimation and forecasting of the technical condition enables to prevent the occurrence of accidents of structures and their associated losses, to use rational use of funds for current and capital repairs, and to regulate the technical condition in such a way as to achieve the most effective use of fixed assets.

Building Reconstruction

The preservation of heritage buildings is beyond doubt an important problem of today. The examination of a heritage building involves a number of problems, viz. missing design documentation, the need to find extant reports about technical condition of the building structures and building reconstruction projects prepared by different organizations, and nonconformance of data contained in drawings and documents of different organizations. In this paper the abovementioned problems are reviewed exemplified by the case of the federal heritage-listed building "Ekaterinburg State Academic Opera and Ballet Theatre", Yekaterinburg. The paper proposes the use of solutions based on information modeling methods for the examination of structures of the abovementioned building and reviews the possibility of employing these methods for upkeeping the building. The article demonstrates the practical value of the proposed application of a BIM model method comprising the building reconstruction stages for the structure survey on a specific example. The method proposed in the paper has a great practical value and can be employed for the improvement of normative and technical documentation, heritage building survey works, and for creating design documentation for restoration of buildings.

Introduction. Reconstruction measures can restore production assets of an enterprise, ensure its economic efficiency, solve transportation and environmental problems. A relevant objective is to identify a set of the most important tasks of reconstruction of an industrial facility. Development of draft design proposals for the reconstruction of industrial buildings is complicated by the fact that a designer has to make a compositional link between “old” and “new” architecture, different in style and functionality, while focusing on the use of the most advanced effective materials and modern industrial structures. The article describes features of technical solutions for facades in the course of the reconstruction of industrial buildings aimed at the improvement of their energy efficiency and safety. Materials and methods. Reconstruction of industrial enterprises performs the function of transformation of industrial areas. Modern industrial architecture is focused on industrial tasks, such as the workplace protection from negative environmental effects (wind, rain, cold); arrangement of effective lighting in the workplaces; rational arrangement of workplaces, office equipment and production lines, auxiliary and service facilities, etc. Results. If there are social, historical, and architectural reasons to preserve a building, it is necessary to reconstruct and improve old industrial buildings and change their technical and economic characteristics. The reconstruction of a building means its modification aimed at changing its functionality in part or in full, taking into account the future prospects of the building. Conclusions. When restoring wornout elements of buildings that have historical significance, new elements are made in such a way that the appearance of a building remains unchanged or looks identical to its original historical appearance. Most industrial buildings, built before the law on energy performance of buildings was enacted, do not meet current regulatory requirements in terms of the thermal protection of the building enclosur.

Quantitative recording of electron patterns and their rapid conversion into digital information is an outstanding goal which the photoplate fails to solve satisfactorily. For a long time, LLL-TV cameras have been used for EM adjustment but due to their inferior pixel number they were never a real alternative to the photoplate. This situation has changed with the availability of scientific grade slow-scan charged coupled devices (CCD) with pixel numbers exceeding 106, photometric accuracy and, by Peltier cooling, both excellent storage and noise figures previously inaccessible in image detection technology. Again the electron image is converted into a photon image fed to the CCD by some light optical transfer link. Subsequently, some technical solutions are discussed using the detection quantum efficiency (DQE), resolution, pixel number and exposure range as figures of merit.A key quantity is the number of electron-hole pairs released in the CCD sensor by a single primary electron (PE) which can be estimated from the energy deposit ΔE in the scintillator,

Buildings preservation by the conversion of their function has become a domain of interest in the field of industrial heritage. Due to the need to expand existing housing capacities in urban areas, a large number of industrial buildings are nowadays converted into multi-family and single-family housing. The paper deals with the analysis of the functional and aesthetic internal transformation of industrial into housing spaces. The research goal is to determine the principles of conceptualization of housing functional plan within the framework of the original physical structure of the industrial building, at the architectonic composition level and housing unit (dwelling) level. Besides, the paper aims to check the existence of common patterns of the aesthetic transformation of converted spaces, examined through three epochs of the development of industrial architecture: the second half of the XIX century, the first half of the XX century and the post-WWII period.
