Overview ? The concern of potential blast threats towards buildings has highlighted a need to improve preparedness and prevention to ensure that building threats do not lead to disasters. CSA S850 standardizes the design and assessment of buildings subjected to blast loads, helping achieve appropriate levels of building safety. While the main objective is to reduce human casualties and damage to assets due to an air blast, the uniform approach provided by S850 can also lead to more cost-effective design and assessment of buildings against blast loads.

Preface This is the first edition of CSA S850, Design and assessment of buildings subjected to blast loads. Scope 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 cannot be predicted with certainty. 3) The performance of the building and the safety of the occupants are functions of the selected level of protection and the design basis threat (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. For additional information on regulatory compliance, see Clause A.1. 1.2 Materials considered This Standard provides design criteria for concrete, fibre-reinforced polymer (FRP), masonry, steel, and wood. This does not preclude the use of other materials (see Clause 9.1). Note - FRP design provisions apply to retrofit only. 1.3 Items not addressed 1.3.1 This Standard does not address risk assessment or apply to biological, chemical, cratering, electromagnetic pulse (EMP), ground shock, fragmentation loads, induced fire, penetration, perimeter security, radiation, or thermal effects of explosions. Note - Although other effects of explosion such as fragmentation loads are important considerations, special design requirements have not been provided in this Standard. 1.3.2 This Standard does not define a design basis threat (DBT). DBT is building and project specific and it should be specified by the building Owner and/or the authority having jurisdiction. 1.4 Terminology In CSA Standards, \"shall\" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; \"should\" is used to express a recommendation or that which is advised but not required; and \"may\" is used to express an option or that which is permissible within the limits of the standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.5 Units of measurement Equations appearing in this Standard are compatible with the following units: a) area: mm2 (square millimetres); b) force: N (newtons); c) length: mm (millimetres); d) mass: kg; e) moment: N*mm (newton millimetres); and f) stress: MPa (megapascals).
