Abstract

The cross-rod system under consideration is widely used in various fields: industrial and civil construction, aircraft and shipbuilding. There are a large number of methods for calculating these structures’ types, based on differential dependencies system of the 4th order, describing the bending of a flat covering. However, the main reason in solving problems for calculating cross-rod systems is the complexity of mathematical calculations and a large amount of labor, since the system is statically indeterminate. It leads to a large number of linear equations’ systems solution with boundary conditions. The use of computers in the calculation of cross-rod systems allows you to make both dynamic and static calculations of building structures with high accuracy. At the same time, simplified ideal schemes are used in the calculation of structures, where the elements are connected to each other either rigidly or pivotally. In real designs, the connections are elastic and cannot always be replaced with ideal analogues, used in the design schemes. The use of ready-made laminated structures allows reducing not only the cost of production, labor intensity and construction in general, but also the totality of all factors, such as the timing of construction and installation work on the reconstruction and overhaul of buildings and structures.
