Mathematical Models for Calculating Structures Under a Combination of Loads

Abstract

The chosen direction of work, the loads acting on the structure, including some long-term ones, are of a random temporary nature. An unfavorable combination of several random loads over time has a low probability. The work of combinations of snow loads is devoted to solving the problem of combining loads. The combination coefficients largely determine the magnitude of the loads on the structure, and therefore its parameters, material consumption and cost on the one hand; on the other hand, the correct assignment of these coefficients ensures the reliability of the structures. The insufficiency of statistical data on loads and the imperfection of theoretical load models forces designers to create structures with a certain margin to compensate for these shortcomings, which leads to waste of materials. In the design standards in force in our country, when calculating structures and foundations for the action of two or more temporary loads, combination coefficients (...) 1 are introduced, which multiply the design values of each of the existing loads
