Overview
Concrete generally provides adequate fire resistance for most normal applications. However, the strength of concrete decreases at elevated temperatures due to chemical and physical changes. In addition, spalling of concrete occurs in fire which potentially leads to the exposure of the main reinforcements within the concrete to fire.
Controlling the susceptibility of concrete to spalling during fire exposure is one of the major issues in the design and construction of concrete structures and infrastructure today. Real fire scenarios indicate that the fire-induced spalling of concrete is capable of producing serious consequences. In this seminar we discuss this phenomenon and look at what needs to be considered when designing buildings and civil infrastructure for fire resistance.
This technical event is a great opportunity for construction professionals and academic researchers to get up to date with recent achievements in the fire resistance of concrete and the state-of-the-art fire testing facility in Australia.

Professor Maurice Guerrieri (Victoria University)
Associate Professor Dr Maurice Guerrieri (BEng, PhD, Monash) is a structural engineer with specialty in concrete spalling. He is the chief investigator for structural fire testing at Victoria University and has collaborated with world leading fire testing facilities around the world. Associate Professor Maurice Guerrieri has developed the only facility in Australia with the ability to test full scale structurally loaded concrete tunnel segments under fire and has been involved with a number of major infrastructure tunnel projects throughout Australia.
Topic Title
Design of the Metro Tunnel Project Tunnel Linings for Fire Testing
About this Presentation
In this presentation, Maurice will showcase state of the art structural fore test capabilities now available at Victoria University.
With a growing pipeline of major transport infrastructure projects transforming Victoria's road and rail networks, there is an increase in demand for the construction of underground tunnels using the shield tunnelling method. Such tunnels need to be designed for fire resistance in order to preserve both structural integrity and serviceability in the event of a fire event. This paper describes the approach taken to design the concrete tunnel lining segments for Melbourne's Metro Tunnel Project for structural stability during a severe fire incident. Two types of fire testing programs were implemented, both of which used the RABT ZTV (rail) fire curve. The first involved the fire testing of 12 unloaded flat panels in order to determine whether a particular concrete mix design would be susceptible to spalling. Second, six prototype full scale tunnel lining segments were subjected to full scale structural fire testing, for the first time in Australia. The results indicated that full scale structurally loaded fire tests are essential as unloaded flat panels underestimate the degree of spalling. Addition of PP fibres are successful in mitigating spalling in addition to using pozzolans cements such as fly ash and slag.
Jonathon Barnett (Basic Expert Pty Ltd)
Dr Jonathan Barnett is an internationally acclaimed technical expert in fire safety engineering with over forty-two years’ experience in his field. Previously a professor at WPI in the United States, Jonathan has researched topics such as computer modelling of fire, structural fire protection, combustible cladding and the development of new fire test standards.
Starting in 1992 he has worked with the CSIRO, the University of Melbourne, Victoria University, the University of Newcastle, the Australasian Fire Authorities Council, and fire brigades in Victoria and New South Wales. Jonathan is a chartered professional engineer who has designed numerous commercial, residential and special purpose buildings. He is a leader in building defect rectification strategies.
As a forensic specialist, Jonathan has worked on numerous projects both large and small, including the analysis of the events of 9/11. As part of the ASCE/FEMA team he testified before Congress on the events that led to the collapse of the buildings at New York’s World Trade Centre.
Topic Title
Fire Safety of Concrete
About this Presentation
Jonathan’s presentation will address how and why we worry about concrete structures in fires. He will explore the changes to the National Construction Code that will require structural engineers to calculate the potential for collapse, not just whether a design is deemed-to-satisfy. Jonathan will round out his presentation with a discussion of some of the most recent trends in the performance of concrete structures as presented at the SIF2020 conference recently held at the University of Queensland.
