| Description
| - Konstrukce s dlouhou životností trpí pomalou degradací v důsledku koroze, karbonatace či únavy, a po určité době musí být opraveny nebo nahrazeny novým objektem. Kritériem pro navrhování a údržbu je (kromě bezpečnosti) efektivnost nákladů, charakterizovaná pomocí prostředků vynaložených na jednotku provozu. Nová konstrukce by měla být dimenzována tak, aby zaručila minimální jednotkové náklady. Příspěvek přináší vztahy mezi rozměry, životností a náklady pro základní případy degradace, a analyzuje optimální životnost pro typická rozdělení napětí a způsoby degradace. Absolutní minimum lze docílit jen v některých případech. Rozhodování o opravách jsou usnadněna návrhem několika variant a porovnáním jednotkových nákladů. (cs)
- Long-life structures suffer by gradual deterioration due to corrosion, fatigue or carbonatation, and after some time they must be repaired or replaced by a new object. In addition to safety, a criterion for design and maintenance is cost effectiveness, characterised by the total money expended per unit time of service. A new construction should be dimensioned so as to ensure the minimum unit costs. The paper brings formulae relating the dimensions, lifetime and costs for basic forms of deterioration function, and analyses the problem of optimum life for typical stress distributions and deterioration rates. Only in some cases can the absolute minimum be achieved within a suitable interval of sizes and service times. Decisions about repairs are facili-tated by proposing several variants and comparing the costs per unit of service, calculated from those for operation, inspections, maintenance and repair, with respect to the time value of money.
