Reliability of steel structures in compliance with the principles of the EN 1990 - Theoretical and Experimental Studies, Part 2

Original language description

The steel structures design standard EC3 allows, for frame structures with compression members, to determine the load carrying capacity both by the stability solution with buckling length and by the geometrically nonlinear solution with initial imperfection. On the example of two types of steel plane frames, it will be demonstrated how the solutions presented result in different load carrying capacity values. The frame loading will consist of both permanent active component and variable active componentt. Further on, the unbalance of failure probability in dependence on the relation of both loading components will be analysed. A geometrically and physically nonlinear solution was applied to the probability analysis. The numerical simulation method Importance Sampling was used which made it possible to determine, with advantage, the failure probability even on a relatively low number of simulation runs. The input random quantities were considered both according to histograms determined

Czech name

Spolehlivost ocelové konstrukce v souladu s principy normy EN 1990 - Teoretické a experimentální studie, Část 2

Czech description

Postupy normy EC3 umožňují analyzovat únosnost ocelové konstrukce jednak podle stabilitního řešení se vzpěrnou délkou, jednak podle geometricky nelineárního řešení s počáteční imperfekcí. V článku je ukázán příklad spolehlivostní analýzy ocelového rámu,ve které byly všechny vstupní veličiny uvažovány jako náhodné. Je studováno jak se jednotlivé metody a články norem podílejí na spolehlivosti návrhu. Byla použita numerická simulační metoda Importance Sampling.
