Abstract
The investigation method developed in order to validate the bearing
capacity of a three-arcade 18* century stone bridge for the passage of 2^
class loads lends itself to a generalised use for a type of structure that is
very common over the entire Italian territory. The exact 3D geometry of
the arcades of the bridge was determined in situ, by taking into due
account irregularities due to the construction process. The actual
consistence of the masonry of the piers, arches, tympanums and
buttresses was determined on samples and cores. The dynamic behaviour
of the structure was evaluated in both environmental and random
conditions (under heightened traffic levels) with the aid of
accelerometers, spectrum analysers and f.f.t
