In Japan, social needs for the building seismic performance are changing not only to the life safety but also to the maintenance of functionality after the earthquake. So the human condition during building shaking by earthquakes is also beginning to be considered as a part of the functionality of the building.
The Great East Japan Earthquake is mentioned as an example that the building shaking by earthquakes affected the maintenance of human physiological functions. Many questionnaire surveys were conducted targeting the Great East Japan Earthquake, and it was revealed that high-rise building users felt fear and anxiety during earthquake.
However, since such questionnaires are limited to large-scale earthquake disasters, there is a problem that answers to relatively small tremors cannot be obtained, and investigation cannot be conducted immediately after the earthquake. Regarding the influence that the earthquake motion has on the psychological anxiety and human physiology, there is a possibility that a correct answer cannot be obtained after a long time has passed since the earthquake occurred. Therefore, we have developed a system for questionnaires in real time after earthquakes for building users. This paper introduces the sense of human vibration obtained by the questionnaire system.
