The increase in complexity of the built environment has increased the need for alternative solutions to the prescriptive approach in designing fire protection. The prescriptive approach, by relying on a member-by-member approach and not being tied to realistic fire scenarios, prevents the designer from examining the actual response of the structure at local and global levels. The prescriptive approach, hence, does not only preclude potential cost-effective solutions but also hides possible structural vulnerabilities to the designer. Several fire-induced structural failures in the past few years highlight the need for changing the modalities of the design of fire protection. Performance Based Fire Engineering (PBFE) offers an alternative to the prescriptive approach, allowing the engineer to develop a safer and cost-effective design tailored to the specific characteristics of the system under analysis. In this study, the benefits of the PBFE approach are presented by analyzing the behavior of a tall building subject to fire hazards. Through the analysis of fires with potential for local or global impact on the structure, the behavior of the structural system is studied both at the member and at the global levels. The analysis sheds light on areas of design that have more or less resiliency in case of fire.
