| 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.

現行の環境振動評価法として代表的な振動規制法に基づく評価法は屋外での鉛直振動に対する評価法であり，また日本建築学会の居住性能評価規準は鉛直，水平方向別の評価法であって，上述のような特徴を持つ環境振動の評価への適用には課題がある．本研究で得られた成果は，人間の心理的反応に基づく合理的な環境振動の評価による問題の効率的解決や，現行の環境振動評価法の改定に資する知見となることが期待できる．
