Proportion piers and wharves to safely resist the load combinations represented by
Tables 3-6 and 3-7. Analyze each component of the structure and the foundation
elements for all the applicable combinations. Tables 3-6 and 3-7 list load factors (f)
to be used for each combination and the percentage of unit stress applicable for
service load combinations.
Equation 3-2
Si or Ui = fD (D) + fL (Lc+I or Lu) + fBe (Be) + fB (B)
+ fC (C) + fE (E) + fEq (Eq) + fW (W) + fWs (Ws)
+ fRST (R + S + T) + fIce (Ice))
where:
Si
= Service load combination
Ui
= Ultimate load combination
fx
= Load factor listed in Tables 3-6 and 3-7
3-5.2
Load Symbols.
The following load symbols are applicable for Equation 3-1:
D
= Dead load
Lu
= Live load (uniform)
Lc
= Live load (concentrated)
I
= Impact load(for Lc only)
B
= Buoyancy load
Be
= Berthing load
C
= Current load on structure
Cs
= Current load on ship
E
= Earth pressure load
EQ
= Earthquake load
W
= Wind load on structure
Ws
= Wind load on ship
