A SIMPLIFIED MODEL FOR THE DYNAMIC
ANALYSIS
OF CABLE - STAYED BRIDGES
George T. Michaltsos
National Technical University of Athens
Abstract. This paper deals with a model,
which simplifies the finding of the natural eigenfrequencies of a cable-stayed
bridge, with dense distribution of cables. Then, it is possible to study
the vertical forced vibrations of the bridge. Finally, an example is given,
which, clearly, shows the simplicity of the method.
UPROŠĆEN
MODEL ZA DINAMIČKU ANALIZU
KABLOVIMA PODRŽANOG
MOSTA
Ovaj rad se bavi modelom koji uprošćava nalaženje prirodnih sopstvenih
frekfencija kablovima podržanog mosta sa raspodelom gustine kablova. Tada
je moguće proučiti vertikalne prinudne oscilacije mosta. Konačno, dat je
primer koji jasno prikazuje jednostavnost metode.
