WEBINAR N
Zoom Webinar , Online, NSW CIA

Overview

Erich Lassnig from Hagerbach Test Gallery in Switzerland will discuss fire safety design in tunnelling. Findings following the devastating tunnel fires such as the Mont Blanc Tunnel fire and the Tauern Road Tunnel fire led to improvements in legislation and fire safety design in Europe and many parts of the world. Following this, Grant Wang and Yuan-Yuan Song from ARUP will discuss methods for risk assessment and the issue of concrete spalling in addition to presenting some interesting case studies.

Overall, this seminar will look at various types of testing for evaluating the fire performance of concrete materials and structures. It will look at the spalling risk of aged concrete structures and mitigation measures.


Concrete material is generally regarded as ‘fireproof’ because of its incombustibility and its high capacity of thermal insulation. However, similar to steel, concrete also loses strength and stiffness with rise in temperature. In particular, concrete can experience severe spalling during fire, which reduces section size and exposes the reinforcing steel to fire attack, thus reducing the load-bearing capacity of concrete structures. 

To mitigate the risk of concrete spalling, active and passive fire protection can be applied and relevant fire testing can be conducted to evaluate the effectiveness of these measures.

Topics

Concrete Fire Testing
Based on the findings of devastating tunnel fires such as the Mont Blanc Tunnel fire and the Tauern Road Tunnel fire in 1999, the legislation and fire safety design for tunnels in Europe and many parts of the world were significantly improved. Fire safety features such as escape tunnels, cross passages and smoke ducts were made mandatory and extensive fire testing had to be carried out to improve the fire safety of the existing tunnel infrastructure as well as the design and construction of new tunnels. Hagerbach Test Gallery, based in the Rheine Valley in the Swiss Alps, next to Zurich, has a long history in undertaking fire testing and fire fighter training for clients within Europe and globally. Erich Lassnig from Hagerbach Test Gallery will provide an overview of the main fire safety design elements in tunnelling as well as the method of fire testing on concrete elements, coatings and other construction elements based on national and international standards.

Fire Safety Design of Aged Concrete Building Structures
Reinforced concrete structures have been widely used for many decades, and some of them have reached or exceeded their design working life of 50 years but remain functional. However, aged concrete may be more susceptible to the risk of spalling in fire due to reinforcement corrosion, surface cracking and many other factors. Therefore, the risk of concrete spalling should be assessed for aged concrete building structures, and additional active and/or passive fire protection may be required to mitigate the risk. Grant Wang and Yuan-Yuan Song from ARUP will discuss methods for risk assessment and provide case studies.
