1.1 SCOPEThis standard provides minimum loads, hazard levels, associatedcriteria, and intended performance goals for buildings, otherstructures, and their nonstructural components that are subjectto building code requirements. The loads, load combinations, andassociated criteria provided herein are to be used with designstrengths or allowable stress limits contained in design specificationsfor conventional structural materials. Used together, theyare deemed capable of providing the intended performance levelsfor which the provisions of this standard have been developed.Procedures for applying alternative means to demonstrate acceptableperformance are also described.

1.2 DEFINITIONS AND SYMBOLS1.2.1 Definitions. The following definitions apply to theprovisions of the entire standard.ALLOWABLE STRESS DESIGN: A method of proportioningstructural members such that elastically computedstresses produced in the members by nominal loads do notexceed specified allowable stresses (also called “working stressdesign”).AUTHORITY HAVING JURISDICTION: The organization,political subdivision, office, or individual charged with theresponsibility of administering and enforcing the provisions ofthis standard.BUILDINGS: Structures, usually enclosed by walls and aroof, constructed to provide support or shelter for an intendedoccupancy.DESIGN STRENGTH: The product of the nominal strengthand a resistance factor.DESIGNATED NONSTRUCTURAL SYSTEM: A nonstructuralcomponent or system that is essential to the intendedfunction of a Risk Category IV structure or that is essential toLife Safety in structures assigned to other Risk Categories.ESSENTIAL FACILITIES: Buildings and other structuresthat are intended to remain operational in the event of extremeenvironmental loading from flood, wind, snow, or earthquakes.FACTORED LOAD: The product of the nominal load and aload factor.HIGHLY TOXIC SUBSTANCE: As defined in 29 CFR1910.1200, Appendix A, with Amendments as of February 1,2000.

IMPORTANCE FACTOR: A factor that accounts for thedegree of risk to human life, health, and welfare associated withdamage to property or loss of use or functionality.LIMIT STATE: A condition beyond which a structure ormember becomes unfit for service and is judged either to be nolonger useful for its intended function (serviceability limit state)or to be unsafe (strength limit state).
