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.

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.
