Model Description

Model Form

$$q = {1 \over 2}\rho \cdot {V^2} \cdot {C_e} \cdot {C_g} \cdot {C_p} \cdot \varepsilon $$
• For further information on this model, refer to Mahsuli, M., Haukaas, T. (2013).

DDM sensitivities

• No

Properties

Object Name

• Name of the object in Rt
• Allowable characters are upper-case and lower-case letters, numbers, and underscore (“_”).
• The name is unique and case-sensitive.

Display Output

• Determines whether the model is allowed to print messages to the Output Pane.

Velocity

• \({V}\) = Wind velocity

Air Density

• \({\rho}\) = Air density

Exposure Factor

• \({C_e}\) = Exposure factor

External Pressure Factor

• \({C_p}\) = External pressure factor

Gust Factor

• \({C_g}\) = Gust factor

Epsilon

• \({\varepsilon}\) = Model error

Output

• \({q}\) = Wind pressure
• The output is an automatically generated generic response object, which takes the object name of the model plus “Response”.
