Time Variant Analysis of Structural Reliability - Numerical Comparison of Various Approaches

Popis výsledku v původním jazyce

Civil engineering structures are often exposed to combinations of time-variant loads. Random load fluctuations within a working life may be well described by rectangular wave renewal processes with intermittencies. The present study is aimed at comparison of techniques provided by Melchers (1995), Rackwitz (1998) and Sykora (2005). In addition estimates based on the rule proposed by Turkstra (1970) are provided. Reliability analyses of simple structural members and structures indicate that the upper bounds by Melchers and Sykora are in a good agreement, providing results close to the exact solution. Also Turkstra's rule seems to be sufficiently accurate for civil engineering applications. However, the expression provided by Rackwitz may not lead to anupper bound on the failure probability particularly for the combination of spike-like processes.
