| Abstract. | Problem statement. The purpose of the study is to determine the resource of individual racks of mobile rod structures from the construction forests of Layher, and the entire structure taking into account the detailed modeling of elastic nodes, taking into account the off-center application of compressive loads and allowed curvature of the axis of the racks. Results. The main results of the study are that in determining the stability reserve at repeated static loads to ensure a given level of reliability, a two-way interval evaluation of both the results of modeling random loading values of compressed elements of the racks and their maximum load-bearing capacity is necessary. The stability reserve, therefore, is a random value that depends not only on random loads, but also on random values of the eccentricity of the application of loads and random curvatures of the axis of the elements of the racks. As a failure for the calculation of the minimum resource of the element and structure as a whole, the condition of exhaustion of the stability reserve to zero in at least one element of the racks with a uniform distribution of the strength of the elements of the racks is accepted. Conclusions. The significance of the results for the construction industry is that the developed algorithm for solving the problem of studying the changes in the stability reserve of the elements of the racks and the structure as a whole provides the ability to determine and regulate the minimum design life with a given reliability of failure in at least one element of the structure at repeated static loads. |
