Analysis of Security Evacuation Simulation and Optimization of a University Library

Taking a university library as the example, Pathfinder (trial version) was used to make a full size simulation of the library evacuation. The analysis shows that there are some problems: The imbalance in using evacuation staircases, a lack of coordination between the loading number of the north and south area, and the gap between the evacuation ability of the two areas. Schemes have been optimized to these problems. Three scenarios’ escape time respectively is 428.83, 341.13 and 285.28 seconds after optimization. Then advice was put forward, such as strengthening the training for staffs, shutting down some passages reasonably between stairs and floors, and readjusting the reading seats of north and south area properly, etc.
