Özet:

One of the important criteria of the safety of the structures is to ensure safe evacuation. In buildings with high occupant density, the number of factors affecting the evacuation increases. In heritage buildings such as the ancient theater, there may be different problems in evacuation, such as late egress, due to what insufficient egress etc. In this study, the results of the observational evacuation measurement of the normal evacuation after the concert of the Aspendos theater in Turkey, which is the ancient theater of the Roman Period, are presented. The evacuation time of the crowd from the building and the walking speed on the stairs were observed. Obtained results were compared with studies in literature. It is seen that the walking speed is slower than expected due to the architectural features of the theatre such as inappropriate stairs. To ensure safe evacuation in cultural heritage structures without damaging the structure, improvement suggestions can be made regarding guidance for route selection. There is not enough study exists in the literature about the evacuation of ancient theaters. Evacuation works to be carried out in these structures, which are actively used in cultural activities, are important for safe use.
