The term resilience is being more widely adopted in fire safety engineering, however, its comprehensive description is not clearly explained or correctly applied in practice. This study, therefore, defines the categories, dimensions, characteristics, capacities, objectives and missions possessed by resilience to provide a holistic understanding of the term. This is followed by an analysis and classification of the UK Standards and Codes addressing resilience considering their administrative and engineering features of resilience, and their resilience dimensions with definitions of fire resilience measures and approaches. A practical example of a fire resilience framework is applied in educational buildings considering internal resilience for a safe facility, risk reduction and disaster management, and external resilience involving redundancy of resources and community support. Finally, a fire resilience design framework is created in which structural and fire safety engineering are considered clarifying the steps to follow in a comprehensive design process based on a flow chart. This paper will contribute to the creation of a unified terminology and understanding of the concept linked to resilience to be adopted in various disciplines.

“…Moving from a prescriptive approach to performance based design enables designers to apply knowledge of real structural behaviour during fire, while accounting for uncertainties allows designers to quantify the reliability of the proposed solution, as well as the overall level of risk associated with the design, and to more confidently inform any further decision-making based on the results [8][9][10].…”

Probabilistic Study of the Resistance of a Simply-Supported Reinforced Concrete Slab According to Eurocode Parametric Fire

et al. 2018

We present the application of a simple probabilistic methodology to determine the reliability of a structural element exposed to fire when designed following Eurocode 1-1-2 (EC1). Eurocodes are being used extensively within the European Union in the design of many buildings and structures. Here, the methodology is applied to a simply-supported, reinforced concrete slab 180 mm thick, with a standard load bearing fire resistance of 90 min. The slab is subjected to a fire in an office compartment of 420 m 2 floor area and 4 m height. Temperature time curves are produced using the EC1 parametric fire curve, which assumes uniform temperature and a uniform burning condition for the fire. Heat transfer calculations identify the plausible worst case scenarios in terms of maximum rebar temperature. We found that a ventilation-controlled fire with opening factor 0.02 m 1/2 results in a maximum rebar temperature of 448°C after 102 min of fire exposure. Sensitivity analyses to the main parameters in the EC1 fire curves and in the EC1 heat transfer calculations are performed using a one-at-a-time (OAT) method. The failure probability is then calculated for a series of input parameters using the Monte Carlo method. The results show that this slab has a 0.3% probability of failure when the compartment is designed with all layers of safety in place (detection and sprinkler systems, safe access route, and fire fighting devices are available). Unavailability of sprinkler systems results in a 1% probability of failure. When both sprinkler system and detection are not available in the building, the probability of failure is 8%. This novel study conducts for the first time a probabilistic calculation using the EC1 parametric curve, helping engineers to identify the most critical design fires and the probabilistic resistance assumed in EC1.

“…According to Liew 2 the key feature for implementing the performance-based fire design codes is the assessment of the fire resistance of the structure. Johann 3 introduces recent research and discussed a possible approach to integrating fire safety into the design process for structural framing systems. Hoey 4 expresses the benefits of using suppression systems as part of an integrated fire safety strategy in a building.…”

Summarized within the following article are the attempts made over an eight-year time period at the Illinois Institute of Technology to improve the skills of its Architecture and Architectural Engineering Students with regards to the integration of safety and fire protection into the building design process. System integration has long been recognized as the key to an effective and efficient building operating building. The process involved in the integration of a fire protection subsystem, along with additional MEP subsystems within a building is quite challenging, and can have a profound impact on the client's satisfaction. This process becomes especially important once further technological system integration within a proposed building is considered in addition to the possibility of future system upgrades and their incorporation into the structure, as newer technologies enter the market place. The objective of this paper is to discuss the project-based learning integrated with formal lectures approach in which the goal is the integration of safety and fire protection measures into the building design process to achieve the most efficient, economical, and environmentally friendly design. Sprinklers, Standpipes, Fire Pumps, Special Suppression and Detection Systems (CAE 422): review and introduction to fluid dynamics applied to sprinklers, standpipes, fire pumps, and special suppression systems; hydraulic design criteria and procedures for sprinklers requirements, standpipes, fire pumps, special suppression systems, and detection and alarm systems using nationally recognized design (National Fire Protection Association) standards, water supply requirement systems and distributions. Introduction to Fire Dynamic (CAE 424) & Dynamics of Fire (CAE 510): introduction to fire, physics and chemistry, and mass and heat transfer principles, fire fluid mechanic fundamentals, fundamentals and requirements of the burning of materials (gases, liquids, and solids), fire phenomena in enclosures such as pre-flashover and post-flashover.
