1.1 General
This Standard provides criteria for the analysis and design of new buildings and assessment of existing buildings to resist blast loading.
Notes:
1) The main objective of this Standard is to reduce human casualties and damage to assets due to an air blast.
2) It should be recognized that the extent and severity of an explosion and resulting damage cannot be predicted with certainty.
3) The performance of the building and the safety of the occupants are functions of the selected LOP and the DBT.
4) Users should ensure they are familiar with applicable legislation. Where this Standard conflicts with applicable legislation, it is assumed that the legislation applies.
1.2 Materials considered
This Standard provides design criteria for concrete, FRP, masonry, steel, and wood. This does not preclude the use of other materials (see Clause 9.1).
