Currently, bridge constructions in Vietnam, as well as in the world, are
regularly monitored and evaluated to ensure safety in the exploitation process
and to prevent damage. The traditional method of monitoring by geodetic tools
through monitoring cycles often brings results with significant errors, thus not
really representing the performance of the structure and potential damages on it.
Recently, to overcome the factors observed by geodetic methods, sensors are directly located on the construction to monitor the change of parameters, such as
stress, deformation and vibrations. From that monitoring it is possible to assess
the mining safety level of the structure through the data collected continuously
from the sensors. However, the funding needs for each monitoring system and
for each specific project may be very large, not to mention the need to spend a
large amount of resources to maintain the monitoring system for many projects,
including high prices from experts and exclusive distributors. Instead of using
sensors and machines on constructions, the research and application of sensors
placed on a vehicle that often passes on a traffic structure may present several
benefits. In this case, the structures are indirectly monitored through equipment
placed on vehicles moving along the structure. In this work, focus is given on
researching and application of indirect monitoring methods by installing sensors
on vehicles to identify frequency and evaluate bridge structures’ performance.The authors acknowledge the financial support of the project research “B2021-GHA04” of the Ministry of Education and Training Vietnam.
