ABSTRACT

Buildings and other structures are classified based on the risk associated with unacceptable performance of the structure, according to Table 1.1. The risk categories range from I to IV, where category I represents buildings and other structures that pose no danger to human life in the event of failure and category IV represents all essential facilities. Each structure is assigned the highest applicable risk category. Assignment of more than one risk category to the same structure based on use and loading conditions is permitted.
