Pressure Fluctuation On Structures:
Experimental Data Analysis
Author(s)

Abstract
Pressure fluctuations have been recorded on the upstream face of a sill with the
presence of a hydraulic jump. Pressures have been investigated through 12
different flow configurations and in 9 vertical points on the central axis of the
sill. The maximum-recorded value depends both on the sampling frequency and
on the experiment duration: that leads to the question of which pressure value
has to be considered to design the structures. Different models of structures have
been adopted. A comparison with natural frequencies of such structures is carried
out, after performing a scale transformation of both pressures and frequencies
using the Froude similitude, according to different authors. Natural frequencies
of the simpler structures have been computed, while they have been take
