One of the important tasks of modern construction is the search for new constructive solutions and the introduction of new construction technologies. Cross-Laminated Timber (CLT) technology is a new material for Ukraine that has proven itself in Europe and America as effective and environmentally friendly with many advantages. Since CLT panels are not widely distributed, studied and do not contain references in the normative literature in Ukraine, the study of these structures is extremely relevant.

Наведено постановку задачі розрахунку параметрів змінних газових потоків через ділянки газопроводів і компресорні станції як задачі математичної фізики з крайовими умовами, залежними від режимних газодинамічних параметрів. Запропоновано швидкі алгоритми розрахунку параметрів роботи компресорних станцій для різних функцій управління газоперекачувальними агрегатами.

The article presents a theoretical analysis of existing concepts to evaluate the non-failure of RC structures in operation. To perform the analysis, the authors considered a number of scientific works of both Ukrainian and foreign researchers. The main focus was on works in which the model of the stochastic nature of the RC structure operation included random parameters of acting loads, as well as the reserve of its bearing capacity and serviceability (geometric dimensions of cross sections of constructive members, strength and deformation characteristics of materials, etc.).
