Mile Davidović,
Zoran Ristić,
The methods of calculation and analysis of thin-walled elements with variable
and different shapes of the cross sections subjected to dynamic loads are
presented in this work. A particular attention is paid to the influence of the
stresses caused by bimoments and specific elastic and inertial loads during the
oscillations of the elements. The comparative analysis of the behavior of the
elements of different cross section shapes is done. The methods of the frequent
analysis of the behavior of the elements and possibilities of improving the
structure from the point of view of its strength are presented. All calculations
are done using numerical methods with either self made or existing algorithms
for the numerical analysis.
Key words: design resistance, dynamic load,
thin – walled element, complex load, statical analysis, dynamic analysis,
bimoment, moment of inertia, system of diferential equations, numerical methods.
