Probabilistic Analysis of a Frame
Original language description
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. In reliability analysis, the probabilistic models proposed by the Joint Committee for Structural Safety (2001) are used for basic variables. The time invariant reliability 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-year lifetime, obtained values of the reliability index vary within the range from 3.95 up to 5.56. The cross-profile IPE 330 designed according to Eurocodes seems to be adequate. It appears that the time invariant reliability analysis based on Turkstra's rule provides considerably lower values of reliability index than those obtained by the time variant analysis.

Pravděpodobnostní rozbor rámové konstrukce
Czech description
Je ověřena spolehlivost ocelového rámu navrženého podle Eurokódů. Pravděpodobnostní rozbor spolehlivosti je založen na Turkstrově pravidle pro kombinaci časově proměnných klimatických zatížení - zatížení sněhem a větrem.
