Influence of yield strength variability over cross-section to steel beam load-carrying capacity

Original language description

Authors of article analysed influence of variability of yield strength over cross-section of hot rolled steel member to its load-carrying capacity. In calculation models, the yield strength is usually taken as constant. But yield strength of a steel hot-rolled beam is generally a random quantity. Not only the whole beam but also its parts have slightly different material characteristics. According to the results of more accurate measurements, the statistical characteristics of the material taken from vaarious cross-section points (e.g. from a web and a flange) are, however, more or less different. This variation is described by one dimensional random field. The load-carrying capacity of the beam IPE300 under bending moment at its ends with the lateralbuckling influence included is analysed, non dimensional slenderness according to EC3 is =0.6. For this relatively low slender beam the influence of the yield strength on the load-carrying capacity is large. Also the influence of all the

Vliv proměnné meze kluzu na únosnost ocelového válcovaného profilu

Czech description

Autoři článku provádějí analýzu vlivu proměnlivosti meze kluzu po průřezu ocelového válcováného profilu na jeho únosnost. Mez kluzu je zpravidla uvažována jako konstantní po celém řešeném prutu. Ve skutečnosti se však jedná o náhodnou veličinu. Byl proveden podrobný výpočet, který zohledňuje vliv proměnlivosti meze kluzu po průřezu.
