Abstract
This study intends to set a habitability grade based on residents' consciousness on a performance level of environmental vibration.
A sensory test was conducted with forty subjects to investigate the relationship between habitability grade and physical quantity of vertical vibration of floor slabs. The subjects' answered to a questionnaire focused on views on habitability grade of environmental vibration before and after the test. Results of the sensory test and the consciousness survey show that the habitability grade of floor vibration can be set on the basis of perception probability. The authors propose a new habitability grade of floor vibration based on the A.I.J. Guidelines in consideration of this relationship between habitability grade and perception probability.
This study determines specific meanings of habitability grade of environmental vibration based on residents' consciousness, such as a standard level and a request level of a majority of people.
