Probabilistische Nachweisführung bestehender Hochspannungsstahlgittermaste

Probabilistic static calculation of existing high voltage steel lattice towers.

High voltage steel lattice towers are steel constructions. The static calculation happens since 1903 in accordance with several editions of VDE 0210. All editions of this code including the current edition include no consideration of an amount of failure consequences. At all tower locations the same value of probability of failure is targeted. It does not matter whether the location is built-up or there is no admittance of persons. A limit for this everyplace equal targeted probability of failure is certainly unknown. A value for the tolerated probability of failure is commonly not mentioned in codes of civil engineering including the VDE 0210. At tower locations with little failure consequences more resources than necessary will set in. It is possible that these resources are missing at locations with high failure consequences. This paper tells about an optional method for probabilistic static calculation of existing constructions using the example of high voltage steel lattice towers. Subsequently the limited available resources of human society can be used optimally.
