They analyzed the use frequency, evacuation number, and time required for evacuation through staircases and entrances in each fire partition and optimized various evacuation approaches. used the Pathfinder software to simulate the safe emergency evacuation of library buildings. Chen, “ Analysis of security evacuation simulation and optimization of a university library,” Procedia Eng. Owing to the existence of a large number of books and other fire carriers in libraries, the design of safe personnel evacuation has introduced higher requirements and has gradually become a research hotspot domestically and abroad. In recent years, fire accidents have frequently occurred in colleges and universities. A university library has the characteristics of intensive knowledge, intensive equipment, and intensive personnel. The results obtained by this study can provide a theoretical basis for the reasonable planning of evacuation pathways and the future safety management of university libraries.Ī university library is the university’s carrier for the inheritance of culture and deposits and also a location with relatively concentrated personnel. Restrictive measures should be taken when the number of personnel in each layer reaches a certain value. The stacking quantity and location planning of items in the reading area greatly influence the evacuation time. The results reveal that the bottleneck area of evacuation is the indoor corridor and exit of evacuation stairs.

By considering the site personnel load, personnel attributes, evacuation speed, and personnel ratio, a simulation was conducted to analyze the effect of stacked items’ quantity and location and the effect of the number of items, such as tables, chairs, and bookshelves, and other factors on the time required for evacuation through an indoor evacuation passage. The library project of the main campus of Liaoning Technical University was modeled using the Pathfinder software.

To ensure the safety and emergency evacuation of university library buildings and improve the efficiency of safe personnel evacuation after an emergency, this study considered the actual size and volume of university libraries.
