“…Not all engineers engaged in this activity manage to understand that machines fail because their elements have failed first. In the search to improve efficiency, the so-called predictive or proactive maintenance is applied, based on diagnostic techniques and technologies, and reliability (Mosharafi et al,2020). The conventional method to determine reliability is based on time to failure, but it has not demonstrated the expected effectiveness in repairable equipment, as it considers the element a black box, which performs its function until it fails.…”

The application of reliability centered maintenance onrepairable equipment requires that the reliability calculation should not to be based on failure statistics, as in traditional methods, but rather on its condition. The "load vs resistance" method presumesthe comparison of process parameters with carefully selected mechanical properties of the materials. The author proposes the calculation based on parameters monitored for diagnosis purposes. Specifically, he analyzes the erosion of steam turbine bladessubject tothe action of solid particle from the superheaters, which, under certain conditions, grow to critical thicknesses and due to stresssactionscaused by thermal changes, fracture and detach, acquiring such energy that then impacts the surface of the blades causing theirerosion. These phenomena are analyzed and equations are established in relation withthe mechanical properties of the blade metal , with the energy requird by oxide flakes to cause their erosion. An expression has been obtained, allowing for the application of the method, whichd has not been found in analyzed research works.

Bridge construction is one of the cores of traffic infrastructure construction. To better develop relevant bridge science, this paper introduces the main research progress in China and abroad in 2020 from 16 aspects. The content consists of four major categories in 16 aspects. The first part is about the bridge structure, including concrete bridge and high-performance materials, steel bridges, composite girders. The second part is about the bridge disaster prevention and mitigation, including bridge seismic resistance, wind resistance of bridge, train-bridge coupling vibration research, bridge hydrodynamics, the durability of the concrete bridges, fatigue of steel bridge, temperature field and temperature effect of bridge; The third part is about the bridge analyses, including numerical simulation of bridge structure, box girder and cable-stayed bridge analysis theories. The last part is concerning the bridge emerging technologies, including bridge informatization and intelligent bridge, the technology in bridge structure test, bridge assessment and reinforcement, prefabricated concrete bridge structure.
