Blast damage to storage tanks and steel clad buildings
چکیده انگلیسی

The 2005 Buncefield vapour cloud explosion showed the huge cost associated with blast damage to commercial property surrounding a major explosion incident. In most cases there was serious disruption to business activity; in many cases the buildings had to be demolished or abandoned for long periods until extensive repairs were carried out.Another key feature of this and other recent vapour cloud explosions has been the damage done to storage tanks. The blasts almost invariably cause immediate top and bund fires in any tanks surrounded by the vapour – even if they contain relatively high flashpoint materials such as diesel.The first part of this paper describes the patterns of damage observed in buildings in the industrial estates around Buncefield. Methods for assessing the degree of external and internal damage are presented.The second part of the paper deals with failure modes and ignition of various types of liquid storage tank during vapour cloud explosions. Again, the Buncefield data provides excellent examples that illustrate the importance of tank design, fill level, location relative to the cloud, etc.


► Evidence on damage to tanks and buildings at the Buncefield explosion.
► Large portal frame structures are vulnerable to pressures of order 1 kPa.
► Slow build up of pressure leads to a single large vent in one side. Other sides then see reduced pressures.
► Blast penetration into vented buildings is analysed.
► Blasts cause fires in any tanks surrounded by vapour.
