Abstract Group dynamics theory shows that social relationships are an important factor influencing group behavior. The characteristics and changes in social relationships during emergencies were studied in experiments modeling 6 high-rise building emergency evacuations. The evacuees are all from a graduate class with 30 students where are some pre-existing social relations such as friends, girl and boy friends, and roommates. Social network analyses, questionnaires and video data showed that the leader-follower behavior during emergencies may be influenced by the normal social relationships, but that the center of the evacuee group, the group cohesion, and subgroups showed obvious changes. A mutual believed degree (MBD) was defined to identify the opinion leaders in normal situations and in emergencies which shows that the potential leaders in emergencies are most likely from the normal opinion leaders and from the men who run faster in evacuations.
