Ultimate load behaviour of longitudinally stiffened steel webs subject to partial edge loading
 Kutmanová, I. ; Škaloud, Miroslav ; Januš, K. ; Löwitová, O.
The objective of the contribution is to describe the main results and conclusions of a several years' experimental investigation into the ultimate limit state of steel plate girders whose thin webs were loaded by a partial edge load. Altogether 184 experimental girders were tested, with the following geometrical characteristics of the test girders being varied from girder to girder: (i) the depth-to-thickness ratio of the webs, (ii) the flange size, (iii) the position of\nthe longitudinal rib, (iv) its dimensions and (v) the length of load. Special care was given to a study of (a) the\nstiffeners location and size and (b) the dimensions of the loaded flange upon the progression of plastification, the failure mechanisms and ultimate strengths of the girders tested.

Parametric sensitivity analysis of the stress state in the crack-prone areas of breathing webs
 Kala, J. ; Kala, Z. ; Škaloud, Miroslav ; Teplý, B.
Within the framework of the Czech research on the cumulative damage process in, and the fatigue limit state of, steel plate girders under the action of many times repeated loading, the authors decided to perform a sensitivity analysis of the effect of initial imperfections on the state of stress in those areas of the breathing webs of the girders in which fastigue cracks develop under the effect of repeated loads. This paper describes a preparatory stage of the study; in whitch the theoretical apparatus needed is prepared, discussed and calibrated by way of comparing theoretical results obtained with the results of the tests carried out by one of the authors and his co-workers some time ago.

Some remarks in regard to the fatigue analysis of steel plate girders with breathing webs
 Maquoi, R. ; Škaloud, Miroslav
Possible fatgue due to repeated web breathing is reviewed in several respects with the aim to track possible recommendations for a realistic design check of plated structures.
