Abstract
The scientific and technological progress makes it possible to create steel beams of various strength with high efficiency and reliability.Purpose: The bridge construction and operation with bisteel (hybrid) beams include various stages of design to operation, providing the required level of reliability. As a result of design, manufacture and construction of bridges with such superstructures, the reliability is predicted, which manifests itself during the operation.Research findings: The article determines the criteria for trouble-free operation for a given service life, describes and predicts the reliability level based on the limit state of bisteel beams. Using probabilistic approaches and the random nature of loading, the risk of failure is considered in safe operation of the structure, depending on the interaction between elements in the cross section of bisteel beams under loading. The issues of safety, risk, reliability, and survivability of bisteel beams are discussed.
