Abstract
The interaction dynamics between the
bridge and moving vehicles is a complicated
problem in that it consists of two subsystems,
i.e., the bridge and moving vehicles, and that
the two subsystems move with respect to
each other. Because the two subsystems are
elastic bodies, energies of various forms can
be transferred between the two bodies, which
can result in variation of the contact forces.
In the past decade, the principal investigator
and his group have conducted a series of
research related to the vehicles moving load
problems, including both the analytical and
numerical studies. Most of the results have
been published in various international
journals. In this three-year research project,
focus was placed on those subjects not fully
covered by previous studies, as outlined in
the project proposal. However, it is admitted
that in the process of researching, some
minor adjustments are unavoidably made on
the research items, although the main
direction remains basically unchanged. In this
report, only two major achievements will be
summarized.
