Blast Resistant Buildings

The Defender Range of Blast Resistant Buildings have design approval to meet blast resistance criteria under the following conditions:

  • • Walls - Reflected overpressure of 650 mbar for a positive phase duration on 100msec
  • • Roof – The roof for the 650mbar module (reflected on the front face) would need to be able to resist the 320mbar pressure (side on or overpressure) for the duration of 100msec
  • • Floor– Reflected overpressure of 650mbar for a positive phase duration of 100msec
  • • Windows - Reflected overpressure of 650mbar for a positive phase duration of 100msec
  • • Door - Reflected overpressure of 650mbar for a positive phase duration of 100msec
  • • Door has been classified as Category 1

All Blast Resistant Buildings loadings assumed to be of a shock wave form i.e instantaneously rising at time t=0 to the maximum overpressure and decaying linearly to zero mbar at t=100msec
