Function
Apply the nodal load calculated by the user-defined function formula.
Call
From the Main Menu select [Load] tab > [Type : Static Load] > [Lateral] group > [Wind Pressure] > [Function Wind Pressure]
Input
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.
