A world first! Understanding the behavior of high walls in fire, this was the objective of this exceptional test led in CSTB on the Vulcain furnace, at Marne-la-Vallée.

Fire resistance of a 9 meters wall, composed of superimposed reinforced concrete panels, was tested under fire exposure during 2 hours with a thermal strain of 7.2 cm of deflection.

This test validated the simulation method developed by CSTB's team to assess the fire performance of an assembly of panels to better understand the behavior of walls higher than 3 m under fire exposure.
