Matching numerically a rheological model to the Eurocode creep through dynamic analysis

Resumo

A dynamic analysis of vibration for considering a three-parameter rheological model to fit the same
results as predicted for creep by the Eurocode (EN 1992) criteria is performed based on the adjustment of its
parameters. The use of a rheological model of three parameters as a valid alternative for real problems brings a
huge facility for mathematical implementation and manipulation due the simplicity of the solution. For adjustment
of the elastics and the viscous parameters, a numerical simulation to calculate the fundamental frequency of an
actual reinforcement concrete pole is carried out in comparison with the standard Eurocode criteria. In this
determination, the geometry variation, a concentrated force present at the free end of the structural element, and
the self-weight of the structure are considered.
