Abstract
With the development of computer processors, vast numerical simulation tools are widely used by fire engineers to determine the spread of fire and smoke. However, the fire modeling practices are often highly time‐consuming and cost‐intensive especially for building geometry information which does limit the further implementation of building fire safety analysis. Although nowadays building information modeling (BIM) has become a buzzword in the Architecture, Engineering, and Construction (AEC) field to facilitate information integration and interoperability, data sharing and exchange are still weak in the traditional interoperability between BIM applications and fire simulation software, since the data schema of them are totally different. In this paper, a quick and accurate approach for information sharing for building fire safety analysis between mainstream BIM applications and widely used fire simulation software has been successfully implemented, based on Industry Foundation Classes (IFC) and Fire Dynamics Simulator (FDS). And, both geometrical building information and sematic information can be shared by this approach through the transformation of coordinate systems, outer database, and IFC file extension. The BIM model restoring fire simulation results can support other performance‐based design of building, such as structural fire‐resistant design and evacuation design. And, all of the analysis results including building fire simulation, structure safety design, and evacuation simulation can be integrated in Autodesk Revit, establishing a framework of IFC‐ and FDS‐based information sharing for building fire safety analysis successfully. A gymnasium has been taken as a case study to illustrate the capability of this framework.

building information modeling (BIM) (Building Information Modeling) attracts widespread attention and has become a buzzword in the Architecture, Engineering, and Construction (AEC) field, which is defined as a digital model containing all information created or gathered throughout building life cycle and a technology to achieve the information integration and interoperability, which is different from traditional drawingbased or computer-aided design (CAD) technologies-based design and construction methods [1]
Erefore, this paper proposes a comprehensive approach for information sharing for building fire safety analysis between mainstream BIM applications and widely used fire simulation software has been successfully implemented, based on Industry Foundation Classes (IFC) and Fire Dynamics Simulator (FDS)

Erefore, this paper proposes a comprehensive approach for information sharing for building fire safety analysis between mainstream BIM applications and widely used fire simulation software has been successfully implemented, based on IFC and FDS For this purpose, the main objectives of fire simulation analysis based on BIM technology in this paper are to (1) Develop a framework for direct translation of geometrical and semantic building information between BIM applications and fire simulation software to help fire engineers avoid manually reinserting data in fire modeling practices (2) Store fire simulation results into building information model for further information exchanging and sharing to support performance-based design of buildings, including structural fire-resistant design and evacuation design e rest of the paper is organized as follows: Section 2 reviews related works in terms of the information sharing between BIM applications and fire simulation software.
