Study On Safety Evacuation And Fire Smoke Of Antique Buildings

Ancient architecture makes ancient architectural art and folk customs in the integral whole, is a great crystallization of Chinese ancient architectural history, is also an important part of history and cultural heritage of the Chinese nation in five thousand years. With the rapid growth of national economy in China, people’s demand for cultural life is also constantly improving. With the rapid development of tourism, the historical and cultural value and cultural connotation of ancient architecture and villages was excavated by tourism developers gradually. In the renovated ancient architecture, while some of the antique building came into being. As the alternative and traditions of the ancient architecture, antique buildings has been optimize on building materials and plane layout, but there are still fire safety hazards similar to ancient building. In recent years, ancient architecture and antique buildings fire accident frequently happen, it cause irreversible damage to buildings, Our country began to pay greater attention to fire safety research, therefore, it let us realize that analysis of fire hazard and fire characteristics of antique buildings, further study of the safe evacuation and fire smoke movement under fire, It is very important for the protection and safety of antique buildings.This paper takes Beijing Miyun Gubei water town（simatai） international tourism resort antique buildings as the main research object, through the field investigation of Gubei water town, the structural form of the antique buildings and the basic data of personnel characteristic is obtained; LEGION and STEPS, two software are used to build pedestrian evacuation simulation model, evacuation movement time, average space density and the coefficient of Dissatisfaction are obtained through numerical simulation analysis, provided help for the study of the characteristics of evacuation behavior and determination of emergency evacuation plan; Smoke movement in a single antique building was simulated using FDS fire simulation software, the distribution law of smoke spread, flue gas temperature, volume fraction of CO₂ and visibility in the antique buildings fire is studied in order to provide theoretical basis for further safety evacuation route and evacuation plan.
