Dataset_Analysis and Optimization of Fire Evacuation Safety Performance in Large Urban Complexes

This dataset is the BIM of a shopping center in Chengdu, which was selected as the research scenario for personnel evacuation under fire conditions. The shopping center is a four-story frame structure with a total floor area of 11,108 m², with each floor covering 2,777 m² and a floor height of 4 meters. The first floor has seven exits connected to the outside and seven staircases. The shopping center includes various commercial establishments such as leisure tea houses, food courts, and department stores, featuring complete facilities, high customer flow, dense occupancy, and numerous combustible materials. This BIM model was constructed using an architectural template. Grid lines were drawn based on building drawings, with floor elevations and slab thicknesses configured. Wall models were built according to the drawings, with wall dimensions configured and the wall type set as "basic wall." Windows, doors, and staircases were then added. The constructed BIM model was used to create the fire simulation model and evacuation model.<br>
