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.
