Chapter 4 - H: Soil Loads & Hydrostatic Pressure

Loads computed from soil and/or hydrostatic pressure are designated as "H" in the load combination equations.
ASCE 7-05 3.2 treats both lateral soil loads and hydrostatic pressure similarly. Both increase linearly with depth according to the equation
lateral pressure at h = g h
For water, you must also consider the upward buoyancy force, gw hwmax, as well (see ASCE 7-05 3.2.2).
Figure 4.1.1 illustrates the application of the loads.
