Description
  • V tomto článku je studována stabilita dvou základních typů kabelových mostů, zavěšených na jedné a dvou řadách lan. Jsou zkoumány dva linearizované modely centrální mostovky popisující vertikální a torzní kmity. Poté, co jsou tyto modely analyzovány, je zformulováno kritérium stability. Toto kritérium vyjadřuje relaci mezi vlastními čísly vertikálních a torzních oscilací centrální mostovky. Spojitá závislost vlastních hodnot na některých parametrech je studována a problém stability pro centrální mostovku je formulován. Existence řešení problému stability je dokázána. Některé další otázky stability či nestability oscilací jsou rovněž studovány. (cs)
  • In this paper the stability of two basic types of cable stayed bridges, suspended by one and two rows of cables, is studied. Two linearized models of the centre span describing the vertical and torsion oscillations are investigated. After the analysis of these models, a stability criterion is formulated. The criterion expresses a relation between the eigenvalues of vertical and torsion oscillations of the centre span. The continuous dependance of the eigenvalues on some data is studied and a stability problem for the centre span is formulated. Some other qualitative results concerning the stability/instability of oscillations are studied as well.
