Unformatted text preview: Chapter 2 COMBINATIONS OF LOADS 2.1 GENERAL Buildings and other structures shall be designed using the provi- sions of either Section 2.3 or 2.4. Either Section 2.3 or 2.4 shall be used exclusively for proportioning elements of a particular construction material throughout the structure. 2.2 SYMBOLS AND NOTATION D = dead load D i = weight of ice E = earthquake load F = load due to fluids with well-defined pressures and maximum heights F a = flood load H = load due to lateral earth pressure, ground water pressure, or pressure of bulk materials L = live load L r = roof live load R = rain load S = snow load T = self-straining force W = wind load W i = wind-on-ice determined in accordance with Chapter 10 2.3 COMBINING FACTORED LOADS USING STRENGTH DESIGN 2.3.1 Applicability. The load combinations and load factors given in Section 2.3.2 shall be used only in those cases in which they are specifically authorized by the applicable material design standard. 2.3.2 Basic Combinations. Structures, components, and foun- dations shall be designed so that their design strength equals or exceeds the effects of the factored loads in the following combinations: 1. 1.4( D + F ) 2. 1.2( D + F + T ) + 1 . 6( L + H ) + . 5( L r or S or R ) 3. 1 . 2 D + 1 . 6( L r or S or R ) + ( L or 0 . 8 W ) 4. 1 . 2 D + 1 . 6 W + L + . 5( L r or S or R ) 5. 1 . 2 D + 1 . E + L + . 2 S 6. 0 . 9 D + 1 . 6 W + 1 . 6 H 7. 0 . 9 D + 1 . E + 1 . 6 H EXCEPTIONS: 1. The load factor on1....
