| Abstract | This contribution is devoted to issues of long term safe service of high-voltage pylons, which are loaded during service by variable loading with simultaneous acting of external environment. There were proved the procedures ensuring that the limit state will not occur during the period of technical life and the service will be safe for a long time. A draft of diagnostic procedures was elaborated, applied in suitable inspection intervals, following from the analysis of failure risks. The maintenance and repair procedures, assuring the safety of service until next inspection are planned on the basis of application of analytic methods of dynamic fracture mechanics. This procedure of controlled ageing is designed for the new and serviced pylons as well. The controlled ageing at the same time prolongs the technical life of structure with a high measure of safety. Residual life can be determined in each phase of pylon life. Controlled ageing allows saving high economic values at spending considerable lower costs for inspection and maintenance. |
