We propose a novel representative power spectrum density as a specific characteristic for showing responses of spans during a long operational period.
The idea behind this method is to use the representative power spectrum density as a powerful tool to evaluate the stiffness decline of spans during their operation period.
In addition, a new measurement method has been introduced to replace the traditional method of monitoring the health conditions of bridges through a periodic measurement technique.
This helps to reduce costs when carrying out testing bridges.
Besides, the proposed approach can be widely applied not only in Vietnam but also in many other underprivileged countries around the world.
Obtained results show that, during the operational process of spans, there is not only a pure vibration evaluation such as bending vibration and torsion vibration tests but also a combination of various vibration types including bending-torsion vibration or high-level vibrations like first-mode bending and first-mode torsion.
Depending on each type of structure and material properties, different types of vibrations will appear more or less during the operational process of spans under a random moving load.
Furthermore, the representative power spectrum density is also suitable for evaluating and determining many different fundamental vibrations through the same measurement time as well as various measurement times.
