Frequent Service LC: D + ψ 1 L
This load combination is intended for checking the frequent serviceability limit state. It conservatively applies ψ 1 to all live loads, even though the Code technically permits ψ 2 to be applied to accompanying variable actions. The load factors used are:
Balance Loading: 1.0 (std & alt)
Dead Loading: 1.0 (std & alt)
Live (Reducible) Loading: 0.5 (std) & 0.0 (alt)
Live (Unreducible) Loading: 0.7 (std) & 0.0 (alt)
Live (Storage) Loading: 0.9 (std) & 0.0 (alt)
