Application of Performance-Based Fire Engineering to Existing Structures and Forensic Investigations
Performance-based fire engineering (PBFE) has gained attention in recent years as a modern alternative to the conventional prescriptive methods for fire protection design. Acknowledged in the 2016 edition of ASCE-7 code, PBFE provides structural engineers with great flexibility to achieve more rational and cost-effective designs against fire hazards. In addition to applications in design optimization and performance evaluation of new structures under fire, PBFE can be an efficient tool for the assessment of existing structures, including renovation and fire protection, fire risk assessment, post-fire forensic investigation, and post-fire structural assessment. This paper outlines the key steps of the PBFE process to perform fire analysis for both new and existing structures, including simulation of fire scenarios with computational fluid dynamics (CFD) and finite element (FE) analysis of the subsequent thermal and structural effects. An example of a tall building façade subject to fire hazard will serve as a benchmark case to demonstrate how structural forensic investigations can benefit from each phase of the PBFE process. For example, it will be illustrated how fire simulation, complemented with traditional investigational data (e.g. photos, witness statements, etc.), can be used to reconstruct a fire event, or how thermal analyses can be utilized to determine the extent of fire-induced damage.
