In the paper are given basic steps necessary for analysis of strength, reliability and residual lifespan of sluice equipments used in hydroelectric power stations. The analysis is accomplished by numerical as well as experimental methods of mechanics and in some cases simple treatments of classical analytical methods are also used. Sluice gates and quick valves are very important parts of water power stations and their reliability is a key condition for their operation. At the first stage are accomplished numerical computations by the finite element methods that serve for first recognition of critical locations in the structure. In the next step, experimental measurements are used for determination of residual stresses and dynamic loading resulting from operation of equipments. Further computations and measurements are used for refinement of analysis. At the end recommendations for modification of structures for improvement of actual state are given.
