Abstract
This study deals with an analysis of occupant behavior in an office building under fire. The data for this pursuit are drawn from the questionnaire which was conducted on the occupants of 'Fukoku' insurance company building, Osaka, Japan, in which a fire had occured on the afternoon of April 6th, 1978. And the final aim of this study is to find out characteristic behavior patterns between three items of a) individual attributes such as occupation and sex, b) first action after perceiving fire and c) evacuation behavior. In this paper of Part 1, classifications of above mentioned items have been dealt with by using the quantification theories of case 2 and case 3 developed by Hayashi. And as the result, fourteen species of first actions after perceiving fire have been divided into four groups of behaviors which are F1 (take responsible actions), F2 (escape at once), F3 (call to others to escape together, remove valuables or waver in confusion) and F4 (wait for instructions). And eleven species of evacuation behaviors showing the reasons why the occupants had taken the routes to escape from the building have been also divided into five groups behaviors which are E1 (take a predetermined route), E2 (take a shorter route or choose a route instantly), E3 (take a previously indicated route), E4 (run after others) and E5 (follow instructions and guidance).
