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>

本数据集为成都某购物中心的建筑信息模型（Building Information Modeling，BIM），该模型被选定为火灾场景下人员疏散研究的试验场景。该购物中心为四层框架结构，总建筑面积11108平方米，单层建筑面积2777平方米，层高4米。首层设有7个对外连通出口与7部楼梯。该购物中心涵盖休闲茶馆、美食广场、百货商场等多种商业业态，具备设施完备、客流量大、人员密集、可燃物料繁多的特征。本BIM模型采用建筑模板搭建，依据建筑图纸绘制网格线，并配置楼层标高与楼板厚度参数；按照建筑图纸搭建墙体模型，配置墙体尺寸并将墙体类型设置为“基本墙体”，随后添加门窗及楼梯构件。基于搭建完成的BIM模型，可进一步构建火灾模拟模型与人员疏散模型。
