Reliability Analysis of a Steel Frame

Popis výsledku v původním jazyce

A steel frame with haunches is designed according to Eurocodes. The frame is exposed to self-weight, snow and wind actions. Lateral-torsional buckling appears to represent the most critical criterion, which is considered as a basis for the limit state function. Probabilistic models of basic variables proposed by Joint Committee for Structural Safety (JCSS) are used in the reliability analysis. Uncertainty model coefficients take into account inaccuracy of the resistance model for the haunched girder andof the load effect model. The time invariant reliabilty analysis is based on Turkstra's rule for combinations of snow and wind loads. The time variant analysis describes snow and wind actions by jump processes with intermittencies. Considering the 50-years lifetime, obtained values of the reliability index beta vary from 3,95 up to 5,56. The cross-profile IPE 330 designed according to Eurocodes seems to be adequate.
