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)

Note: For mats / rafts this combination is broken into several combinations as no alternate factors are used
