So far the investigation and experimental research aiming at fire mentality and behavior of Chinese are few, so that building performance-based fire safety design in China has to adopt foreign data for reference.The paper comprehensively applies such theories and methods as safety science and psychology, behavior, sociology, etc., carries out study on law of human behavior and evacuation time when buildings are on fire through questionnaire and evacuation drill, and provides basis for fire emergency evacuation plan for personnel and building performance-based fire safety design.Taking students under university education as targets, the questionnaire has been organized three times successively, 3444 valid questionnaires have been withdrawn, and nearly one million investigation data have been obtained.
