Resumen:
Due to the lack of real wind records to perform dynamic analysis of
structural systems, civil and structural engineers commonly use
simplified and conservative approaches to consider the dynamic effects
of wind. With the aim to provide wind records, several studies suggest
that the use of spectral density models and configuration of basic wind
speed and terrain roughness are adequate to simulate the velocity field
of the turbulent wind; however, nowadays there is no enough information
to conclude which is the best spectral density model to simulate wind
records for various configurations of basic wind speed and terrain
roughness. For this reason, in this paper different scenarios are
simulated in order to study the behavior of six spectral density
functions which are frequently used in wind engineering. It is observed
that the models proposed by von Karman, von Karman-Harris and Solari are
the best alternative to simulate wind records.
