Metody rascheta rabochejj armatury kolonn zhelezobetonnykh konstrukcijj, rabotajushhikh v uslovijakh ciklicheskogo nagruzhenija

The methods for determining the allowable number of cycles and the amplitude of the voltage at both hard and soft mode of loading. Analyzed the strength of non-stationary loading conditions. The recommendations for the use of the asymmetry of conditional elastic stresses. A review of domestic and foreign regulations on the subject, as well as on the effect of pre-congestion on the durability of structures operating under cyclic loading.
