The catastrophic fires in European tunnels over
the past decade underline the importance of fire safety for such structures.
The structural integrity during fire is becoming all the more important for
road-tunnel projects in Japan, where no-passing restrictions are being re-evaluated
for vehicles loaded with flammable and combustible substances, while the secondary
lining tends to be replaced with fire protection measures. The authors modified
and experimentally verified the performance of our multi-purpose furnace to
conduct in-house not only ISO 834-type cellulosic fire tests for building members,
but also the tunnel fire protection tests in accordance with the German RABT
curve. |
