Beginning with the 20th century metal structures are widely used in the construction branch in Russia. The reason for it was in the development of calculation methods of structures. Beginning with 1930 and till now a substantial number of the industrial buildings (about 90 %) of production plants have been built of metal structures. The essential part of them - 20…60 % of the whole volume - has block coverings consisting of bearing and braced elements. At the present time the data on the operation duration of industrial structures is not systemized throughout Russia. This data may serve as one of characteristic factors for estimating safety operation level, because while the operation term increases, the wear also increases (mechanical damages), which influences the bearing capacity of the structures. The following article examines the collapse of industrial building coverings that may be accompanied not only by material losses, but also by fatal accidents. Statistical data of damageability of trusses and their elements are presented; the consequences of collapse are examined. The average life time of trusses is determined which is serving as a criteria that characterizes damage accumulation. The nature of the collapse of block coverings is revealed which, in most cases, may be classified as progressive.

Industrial structures are cultural legacy sites in need of protection that carry the social, cultural, historical and architectural properties of their respective eras into the present day. Due to the changing production demands and technology, these structures lost their usage value and have been rendered obsolete. The interventions implemented and new functions provided to ensure the continuity of industrial structures must be in accordance with the character of the building. Our study focuses on the renovation process of one of the first industrial premises of the city of İzmir Alsancak Tekel Storages located in Port Rear Area. Industrial building history in the region dates back to the 1900s, when industrial and storage structures have been built. A new master development plan that entered into force in 1989, conserning the fate of these industrial buildings. As the result of the passed legislation, old tekel storages have been transformed to offices and cultural centres. In the scope of this study the changes that occurred in order to refunction the Alsancak Tekel Storages have been inspected. As a method, a detailed literature review of the history of the region was made, and data on the buildings examined before and after the restoration were collected. As a result, the region’s historical development, status of the buildings before the restoration, architectural quality of the buildings after the restoration and role of the buildings in relation to the city have all been examined and collected data were evaluated comparatively.

The problem of analysis of the resistance to the progressive collapse of the bearing steel framework of industrial building of existing production with a complex structural form with a service life of about 50 years is considered in this article. The main goal was to determine the approaches to such analysis and to identify the degree of survivability of the building. Probable emergency situations associated with the actual condition of steel structures, as well as with new and existing technological processes occurring in the industrial workshop were defined. Under the identified scenarios of emergency situations, the possibility of local damage of steel structures and their individual elements was determined. The extent of the impact of emergency situations on bearing steel structures has been determined. The main provisions for the analysis are presented. As a result, the level of sustainability of the industrial building framework to progressive collapse was defined. As a conclusion, the suggested approaches for performing similar analyses of existing industrial buildings are presented. Also the use of measures to prevent possible damage of structures and accidents, as well as to reduce financial costs during technological renovations without reducing the level of reliability and survivability are justified.

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.

AbstractIndustrial buildings play a major role in sustainable development, producing and expending a significant amount of resources, energy and waste. Due to product individualization and accelerating technological advances in manufacturing, industrial buildings strive for highly flexible building structures to accommodate constantly evolving production processes. However, common sustainability assessment tools do not respect flexibility metrics and manufacturing and building design processes run sequentially, neglecting discipline-specific interaction, leading to inflexible solutions. In integrated industrial building design (IIBD), incorporating manufacturing and building disciplines simultaneously, design teams are faced with the choice of multiple conflicting criteria and complex design decisions, opening up a huge design space. To address these issues, this paper presents a parametric design process for efficient design space exploration in IIBD. A state-of-the-art survey and multiple case study are conducted to define four novel flexibility metrics and to develop a unified design space, respecting both building and manufacturing requirements. Based on these results, a parametric design process for automated structural optimization and quantitative flexibility assessment is developed, guiding the decision-making process towards increased sustainability. The proposed framework is tested on a pilot-project of a food and hygiene production, evaluating the design space representation and validating the flexibility metrics. Results confirmed the efficiency of the process that an evolutionary multi-objective optimization algorithm can be implemented in future research to enable multidisciplinary design optimization for flexible industrial building solutions.

Extreme loading conditions such as man-made malicious actions, fires or natural events could induce local failure mechanisms (e.g., a loss of a member) which may trigger progressive collapse. The design or the assessment of a critical infrastructure needs to address the possibility of such an extreme circumstance taking place during its effective life-time. It is observed that blast-induced progressive collapse mechanisms involve non-linear structural behavior similar to that due to earthquakes. This work focuses on probabilistic analysis of progressive collapse of a typical RC structure, induced by a blast event. The objective is to verify the effectiveness of seismic retrofitting schemes against explosions and the eventual progressive collapse. The probabilistic analysis is performed by taking into account the uncertainties in loading such as planar configuration and amplitude of the blast loading. A standard Monte Carlo simulation method is employed to generate various realizations of the uncertain parameters within the problem. For a given realization, various component-level dynamic analyses are preformed within a certain range of distance, in order to quantify and locate the damage induced by shock wave on structural elements. As a case study, a 5-storey reinforced concrete frame structure designed for gravity loading only is considered. As possible retrofitting schemes, steel bracing, FRP wrapping and RC jacketing are compared. The probability of collapse considering both blast and earthquake for the structure before and after retrofit are compared.

The use of heavy fluids (typically refrigerants) for tests on turbomachinery equipment, like centrifugal compressors, under similitude with real working conditions is a common practice in the test facilities of manufacturers. This practice leads to the release of the test gas to the environment, mainly coming from seals, test circuit connections, valve gaskets and from operations of circuit assembling/disassembling necessary to replace or service the machine under test. The spatial distribution and flow of these emissions inside the test building is a complex issue, which depends on the specific circuit features, location of sources, geometry and openings of the building and variable climatic conditions of the location. For a preliminary assessment of the health and safety conditions, a NIST computational package — including a CFD solver — was applied. The aim was to validate the applicability and reliability of this tool, which was developed for other types of buildings; from the industrial side, knowledge of the diffusion scenario is important to define test protocols to guarantee acceptable emissions levels for manpower in working areas. The industrial building is organized in multiple inside workspaces. The concentration of the contaminant in the area of the test benches, determined by the internal fluid dynamics, is calculated with the CFD solver included in the NIST package. In the building, air motion is only affected by natural ventilation. For this reason, the interactions between the outside and the interior climatic and microclimatic parameters must be considered, taking into account also the different possible assumptions about the daily management of the openings of the building envelope. Several cases of release and dispersion of heavy fluid inside the working areas, under different boundary conditions, were considered. The sensitivity of the results to the different seasonal conditions was assessed and discussed. The complex internal geometry of the building was simulated by a combination of single zone models. The results showed an expectable presence of test gas emissions in the neighborhood of the test area and the possibility of buoyancy effects within the large building. A relatively stable concentration of the test gas emissions resulted from the application of the model, which was affected only by substantial variations of the climatic conditions.

The magnitude and the spatial distribution of wind-induced net pressures (external and internal) on buildings are frequently discussed among research communities and construction industries. This paper deals with this topic based on a case study about an industrial building in Denmark, which was damaged due to the wind impact during a storm when a large part of the roof covering was blown off. In order to detect the reason for the damage the wind-induced loads were studied by i) wind tunnel experiments on the external pressures due to different wind directions, ii) analytical investigations of internal pressure due to envelope porosities and planned openings and iii) numerical analyses for the internal and the external pressure. The Reynolds averaged Navier-Stokes (RANS) method is employed to build a numerical model. The experimental, analytical and numerical results are compared with the indicated characteristic loads from the Eurocode.
