| Outline of Final Research Achievements |
The objective of this research was to propose a reasonable evaluation method for environmental vibration caused by vibration of bridges based on human subjective responses to vibration. Such vibration can have the following characteristics: dominant horizontal vibration which has a transient nature depending on traffic condition, horizontal vibration combined with vertical vibration, and vibration combined with audible noise correlated with the vibration. Subjective responses to vibrations with those characteristics were investigated in laboratory experiments and the experimental data that can be applicable to the development of evaluation methods were able to be accumulated.
