Název v původním jazyce

Sensitivity Analysis of the Effect of Initial Imperfections on the (i) Ultimate Load and (ii) Fatigue behaviour of Steel Plate Girders

Popis výsledku v původním jazyce

The study is divided into two parts: (i) in the first one, the plate girder (Fig. 1) is considered to be exposed to quasi-constant loading (i.e. to loads which are either constant or repeated in a very small number of cycles), while (ii) in the other one, the girder is assumed to be subjected to many times repeated loading.Then it is understandable that the objective of the first part should be to look into the influence of initial imperfections on the static ultimate load of the girder related to the fformation of a plastic failure mechanism in it, while that of the second part was to study the effect of imperfections on the stress state under considerably lesser loads, viz. under such as to correspond to the development of fatigue cracks in the girder and, consequently, to its fatigue limit state. In this case the state of stress was measured by principal surface stresses developing in the crack-prone areas (Fig. 2) of the web ?breathing? under the repeated loads, which ? as was demo
