Development of Probabilistic Design and Analysis Tools for Performance-Based Fire Safety Engineering
New Zealand was one of the first countries internationally to introduce a performance-based building regulatory system in 1991.The flexibility of this new regulatory environment was ideally suited to the emerging field of fire safety engineering and offered the opportunity for innovation and efficiencies to be achieved while still maintaining appropriate levels of life safety. In a situation where one selfcontained New Zealand Building Code applies nationally, coupled with a small market size, the intervening period has provided the ability to thoroughly review the effectiveness of the performance-based regulatory regime. Opportunities for improvement identified by such reviews are being addressed in a number of ways, including the development of a new methodology to demonstrate compliance with the fire safety provisions of the New Zealand Building Code. Part of the infrastructure needed to support the next generation of risk-informed stochastic fire safety engineering regulation in New Zealand is suitable calculation tools. Therefore in 2007, a five year joint research project involving BRANZ Limited and the University of Canterbury was initiated. The project has the overall objective of providing practitioners with new design and analysis tools which will demonstrate that defined levels of fire safety are being achieved in buildings. Specifically, the research project alms to integrate significant enhancements into the deterministic BRANZFIRE computer zone model. This will produce a new probabilistic model that generates outputs in the form of cumulative distribution functions of probability that can be directly compared with probabilistic statements of building fire safety performance. This paper provides a summary of the work involved, giving background to the project and the building regulatory system in New Zealand, as well as details of progress to date of the research.
