Research objective: assessment of the impact of crane loading on safe operation of building by using probabilistic methods; taking into account accumulation of damage in building’s structural elements occurring during operation period. Materials and methods: current computational schemes exploit procedures that do not take into consideration all external effects and changes in structures occurring during operation period of an industrial building. They do not provide algorithms for assessment of spatial response of building’s structures if probabilistic methods are used. Results: the experimental and theoretical research carried out by the author resulted in more precise definitions for computational models and for computational methods of analysis of industrial buildings under the action of various crane loads, including those that are not considered by regulatory documents. The suggested models and methods will enable us to design bearing structures of frameworks in accordance with their real operating conditions. The data obtained in a number of full-scale experiments lead to the conclusion that the amplitudes of vibrations caused by lateral forces when the overhead crane travels with a skew are significantly larger than the amplitudes observed during deceleration of the crane trolley. Conclusions: a hybrid algorithm has been developed; the suggested algorithm implements a complex of procedures for assessment of changes occurring in frame structures under different loading scenarios, during the service life of an industrial building.

The article presents the results of evaluation and prediction of reliability a building of the ship hull shop of Astrakhan sea plant under the action of complex combination of stresses. Basing on the values of geometric and stiffness characteristics, a computational model of the object of the study was built. The results were obtained in the course of realization of the method of limiting states, taking into account the random character of the current loads and the strength properties of the materials. Their reliability was confirmed by a multiple conduction of the searching algorithm of mathematical expectations and indicators of variations in the calculated parameters of building structures and operating loads. Numerical characteristics were determined by the results of two surveys of natural oscillations of the framework. During the study the authors evaluated stress-strain state of the building of the ship hull shop both taking into account seismic disturbances and their absence. The calculation of the perception of the seismic load was carried with choosing the earthquake model implementation by mapping the impact of the earthquake in the form of a set of random processes with defining spectra of the input and output. The presented results were obtained by the complex automation of calculating integrated indicators. Its components are: safety factor, depreciation rate of structures, reliability index and the residual resource of the framework. When predicting the durability of the research object the correlation dependencies are built in the form of: a fictitious function of generalized load; time function of stress; generalized function of the reserve coefficient; function of working capacity of the carcass structures; function of the reliability index. The developed algorithm for estimating the reliability of an industrial building can be adopted for use as a tool for further research. Its implementation allows accurately tracking the kinetics of the stress-strain state of individual elements and the overall framework of a particular object in the time of operation.

The article raises the problem of increasing the reliability of an industrial building bearing the entire set of frame disturbances. One of the ways to solve it is to mount extra structural elements, previously unrecorded in the design of the object. During the study we examined some of them: installation of mechanical transverse stiffening diaphragms; increasing the rigidity of the column part above the crane; arranging connecting rods located in levels of covering in the temperature seam and crane beams. Choosing the most effective option is determined by constructive and technological features of the research object. In our case, it acts as a one-storey industrial building of hull workshop of Astrakhan maritime shipyard, equipped with overhead cranes. Using this example the calculations, which were carried out, allow estimating the effect from acceptance of constructive solutions for installation of reinforced concrete diaphragms of stiffness at the edges of framework and increase the rigidity of the column part above the crane. During the study four options are considered for calculation scheme using wall panels. These should include representation of the device: as a solid wall; in two columns wide; for large aperture sizes; at the low altitude of the end of the opening. We have presented a comparative analysis of the results before and after the introduction of the corresponding elements in the calculating model of the research object. In the accepted system of constructive measures disc coating with high horizontal rigidity distributes the load on the front diaphragm. Increasing the stiffness of above the tower crane column part gives an additional effect, as an overhead crane is located closer to the cover and in case of the column of more developed section in the above the crane area, it passes the covering greater effort. In its turn, it prevents the transverse displacement and rotation, involving the entire framework into operation. The introduction of these measures contributes to: equal declining of displacements of stresses loads from the action of the nodal points of the frame, both in the level of brake beams and in the surface level; increasing the period of achieving the object’s maximal allowable condition and an extended period of its faultless operation.

When designing load-bearing framework structures using the method of limiting states it is necessary to determine the maximum possible value of snow load for the entire period of operation of an industrial building for the possibility of transition. The magnitude of the snow load is randomly changed over the time, and therefore the most appropriate form of its display is a probabilistic model of random process. The authors have identified the most preferable approach to modeling of snow load. It consists in presenting a selective sequence of the year maximums in the form of a continuous random variable distributed according to the Gumbel law. Its parameters are expressed through the mathematical expectation and the standard sample set of meteorological observations. According to the calculated values of the parameters the authors have built a graphic interpretation of the law of distribution of this random variable. When building a model of the total snow load on the roof of a building the influence of various factors should be considered, such as: • snow shedding at a given roof slope; • snow movement caused by wind; • distribution of snow depending on the roof shape; • snow melting depending on the thermal characteristics of the roof; • the ability to drain meltwater from the surface of the roof. The resulting model of snow load is adapted for implementation using software complex “DINCIB-new” developed by the authors. The proposed approach to the modeling of the snow load on the roof of an industrial building allows correlating the repeatability period of its limit calculated value with the residual life of the research object. This has become possible due to the multiple implementation of an automated algorithm for calculating an industrial building, which was developed by the authors, with account of the varying values of snow load in relation to the corresponding mathematical expectation, with registering the quantities of other components of the generalized load.

Geometrical characteristics of obstacles on the ground, which determine the roughness of the terrain, cause the air flow turbulence. The friction level of air flow on the surface depends on the height and density of the location of obstacles, which determines the magnitude and direction of the load on a corresponding specific object. Any obstacle located in the way of the turbulent flow experiences a corresponding wind load. In the given study we have considered a multi-span one-storey industrial building as an obstacle. In order to estimate the load on the object of study caused by the wind, we decomposed the corresponding load into two components: middle and fluctuating. The first one shows the static wind load characteristics estimated according to the territorial division into districts of the Russian Federation, where the areas of calculated values of wind pressure are exhibited. Their distribution is the result of the implementation of the probabilistic model presented in the form of non-stationary random field of wind flow speeds. In order to obtain calculated values and automated processing of the value of wind load on the surface of an industrial building under blow the profiles of wind flow velocities at different heights were approximated. The resulting functional dependency on the heights is of a distinct power character. In order to describe the dynamic parameters of the process, presented in the form of the fluctuating component of wind load and the resulting reactions of structural elements of the building, we considered the random functions according to the time parameter. They represent the energy spectrum of the proportion of the wind flow power, attributable to an infinitesimal frequency band. The set of reciprocal spectral densities when selecting the points in space, each of which determines the correlation degree between the states of a random process, has allowed establishing the magnitude of the correlation coefficient of wind pressure pulsations to the entire surface of the building. When studying wind load impact on the operation of an industrial building framework, the corresponding response elements of the system are defined separately from the effects of the average and the sum of pulsation components. The combined effect which corresponds to the most unfavorable load value is achieved in case of coincidence of their signs. The present approach to the assessment of the forces caused by wind and the response to them on the part of the object became the basis of the calculation methodology as one of the components of the generalized load on the object of study.

An accumulation of defects caused by the action of the loads both man-made and external leads to a decrease in the carrying capacity of the carcass structure during operation of industrial buildings. Most notably this problem manifests itself in the buildings equipped with crane equipment. During operation the columns and crane girders obtain significant deformation, and this entails a reduction in structural stiffness characteristics. At the same time a load factor is enhanced when using heavier equipment. Therefore, the main purpose of this study is to identify the opportunities to ensure the reliability required for an industrial building equipped with overhead cranes. The study has developed a complex of calculation methods, the main task of which is to estimate the residual resource of a specific period of technical system operation, taking into account the random nature of a whole set of disturbances. The analysis of the results obtained by the consistent implementation of these techniques allows tracking the dynamics of changes in the stress-strain state of load-bearing structures of industrial objects in operation.In order to solve the problem of providing rigidity frames and improve the reliability of their safe operation the authors propose constructive measures to slow the rate recorded in the calculation of the bearing capacity loss of the system. For this aim we suggest setting the end face transverse stiffening diaphragms, increasing the rigidity of the column above the crane, arranging some connecting rods in the temperature seam, located in the levels of coating and under crane beams. These measures should be used together, which allows achieving a significant effect in providing transverse rigidity. The coating disk with a sufficiently high horizontal rigidity is able to transfer a portion of the load acting on the transverse frames on transverse end faces of the diaphragm. The binder rods prevent relative lateral displacement of the temperature blocks relative to each other, thereby they put the entire frame under the action of horizontal crane loads into operation. Increasing the stiffness of the column above the crane allows transferring a significant part of the effort to the coating when the bridge crane has close proximity to the coating.The proposed constructions are easy to manufacture and do not require the device holes, which weaken the structure. They can be made not only while erecting the buildings, but also in the already constructed ones by increasing the carrying capacity of the overhead cranes. In this paper we evaluate the effectiveness of the proposed measures to improve the structural rigidity of frameworks on the example of several industrial buildings. The comparative analysis of the results obtained before and after the introduction of affirmative action has shown that their arrangement reduces the horizontal displacements of the frame, in the level of crane girders, and the level of coating, with a larger effect observed in the buildings with heavy-duty overhead cranes. This reduction of displacement involves the growth of bending moments values in above the crane column part and the reduction of the magnitude moments in the under crane part. At the great height under the crane portion of the column in most buildings these changes can save generally significant amounts of steel for the framework.Thus, the proposed technical solutions are aimed not only at extending the safe operation of industrial buildings, but also have a positive effect in case of re-production associated with an increase in the lifting capacity of crane equipment, with little financial cost.

This paper considers and asserts the need to obtain the results of inspection of a building at the stage of its commissioning in order to apply comprehensive methodology for assessing its residual life. The author proposes to build regression relationship by correlating the levels of the time series dynamics of stress at certain points of the object calculation scheme considering the results of subsequent surveys. It allows estimating the wear rate of structural elements. The assessment of the reliability and durability of the building frame in a deterministic form is based on the limit states method. The application of this method allows taking into account the random nature of not only the combination of existing loads, but also the strength properties of construction materials by creating a system of safety factors.

The number of accidents at construction facilities has increased dramatically over the recent years. The engineering analysis of the reasons of accidents in the Russian Federation has revealed that the majority of accidents are caused by the loss of stability of specific structural elements, and a substantial reduction of the bearing capacity of structures. At the same time, no proper methodologies of processing and analyzing the results of inspections of structures, or methodologies of assessing the residual service life of structures are available, although advanced diagnostic tools are at hand. Therefore, advanced methods of accident risk analysis assume importance.
A quantitative assessment of the risk exposure of buildings and structures at any stage (design, construction and operation) can only be made through the employment of probabilistic calculations, especially if extreme loads are in the focus. Probabilistic methods are more robust as they evaluate the safety as the possibility of failure. Parameters are treated as stochastic variables.
Based on the research completed by the authors, a 3D computational model of a single-storey industrial building has been developed. The software programme developed by the authors is designated for the resolution of a wide range of problems of reliability, durability, stability and accident risk analysis in respect of buildings exposed to various internal and external loads.
The software may be used to resolve both direct and inverse problems. This feature is highly relevant in assessing structural behaviour. Their structures may constitute defects that affect their rigidity, strength and stability. The behaviour pattern of a loaded structure may be identified by means of an experiment, and thereafter, its rigidity may be identified by resolving the inverse problem in order to assess the life span of the structure.

In the course of construction and restructuring of unique buildings and structures, any architect
faces the need to design complex surfaces that have curvilinear geometrical forms that cannot be
neglected. In turn, designs with complex curvilinear geometrical forms require higher skills in their
development, as the complexity of their design and implementation is a lot higher than that of elements
that have flat surfaces.
The value of plaster cannot be underestimated. Plaster applied to surfaces of various buildings
and structures (walls, partitions, columns) flattens the surface, shapes it up and protects it from
moisture and fire; it improves resistance to heat transfer; it reduces air permeability and improves
the soundproofi ng properties of protected designs, etc.
All pre-set parameters of plaster are to constitute the subject of random inspections, and inspection
results are to be considered in the course of acceptance of any work. The most important
though hard to control parameters of plaster include:
bond strength, thickness, moisture content and density;
flatness or its radius of curvature;
deformation properties of the plaster layer versus deformation properties of the design.
Control over compliance with the design is hard to implement as curvilinear surfaces are located
at a significant height above the ground and/or the floor level. Therefore, there is a need to develop a
non-destructive method of quality assurance of construction, restructuring and finishing works.
The solution to the problem becomes possible due to development of specific hardware and
software designated for remote though accurate identification of the surface curvature.
The authors have developed a modified range-oriented laser methodology that employs angular
segments to remotely assess the flatness of the building structure and its radius of curvature and
to determine the deviation of its value from the designed one. The software also makes it possible
to implement the quality control of the work performed over the curved surfaces coated with various
types of plaster.
The proposed solutions have been pilot tested in practice, and they are ready for use in the
building industry, namely, in construction, repair and restructuring works.
