SUMMARY
This Report describes a project to examine the explosion test results obtained at Spadeadam in the 1990's from the point of view of structural response. BP supplied the Flame Acceleration Simulator (FLACS) pressure traces corresponding to the experimental results obtained at the time. This enabled a comparison to be made between experimental and simulated traces taking into account the target structures' dynamic characteristics and plastic reserves of strength. The main objective of the project was to derive static design pressures for sizing main structures and barriers.
The comparison Response Spectra has given a more robust measure of the conservatism or otherwise of the simulation traces than direct comparison of simulated and experimental pressure traces would yield.
