Function Wind Pressure

Apply the nodal load calculated by the user-defined function formula.

From the Main Menu select Load > Static Load > Lateral > Wind Pressure > Function Wind Pressure.

Function Wind Pressure

Load Case Name

 Select the Load case.

 To enter, modify or delete additional load conditions, use the button.

Direction

Select the direction of wind load action.

X-Y: The load is applied in the horizontal direction of the structure (parallel to the XY plane of the global coordinate system).

Normal: The load is applied perpendicular to the ground.

Angle

Enter the wind load input angle about the global coordinate system X-axis.

Inner Pt.

It is activated when Nomal is selected in Direction field.

Selects the internal node of the structure.

When Inner Pt. is recognized as the inside of the structure and the load is inputted to the designated area, the load is applied from the outside to the inside of the structure.

Scale factor

Enter the increase/ decrease coefficient of wind load.

Function Name

Select the function name defined in Wind Pressure Function from Load> Lateral Loads> Wind Pressure> Wind Pressure Function.

Center Point

It is activated when the wind load function is generated  as Cylindrical Coordinate System in the Wind Pressure Function.

It is the standard node of the radius R and Z.

Selection

Select the area where wind pressure will be applied.

The selected area is calculated as the distributed wind load and the load will be applied on the nodes composing the area.

Group: Enter the load on the Area plane set in Loading Area Plane.
(If the selected area is twisted more than 3 degrees, the load can not be loaded. .)

Element: Enter the load in the closed area created by the selected line element of the structure.

Loading Area Group Name

Select the Area Group which is defined from Structure> Group> Define Loading Area Group.

Element Defining Loading Area

Activated when the element is selected in the Selection field.

Select the line element composing the closed area.
