5	Special Structure	Structures that have special functions or whose failure poses catastrophic risk to a large area (e.g. 100km2) or > 100000 people. Dams, extreme hazard facilities.

Are the columns to be located near a crest or edge of an escarpment?

YesNo

Assumed Topographical Multiplier

Topographical multiplier defaults to 1, design assumes flat terrain sloping less that 5%. Please alter if applicable

Assumed Directional Multiplier

Assumed Shielding Multiplier

Directional and Shielding Multipliers default to 1, design assumes omnidirectional wind and no shielding from adjacent structures. Please alter if applicable.
