Probabilistic approach in the dynamic reanalysis

Abstract

The methods of structural dynamic modification, especially those with their roots in finite element models, have often been described as reanalysis. The paper will discuss the introducing of a probabilistic treatment of important problem parameters. Based on the investigation performed in the [26], further research included the execution of simulations kinetic and potential energy, growth rates Ek and Ep, differences in growth rates, first frequency in a cantilever beam and a modified beam for 1000 values of Young’s modulus of elasticity according to the Gaussian distribution.
