Nodal Wind Pressure

Function

Input the wind load to a frame structures of arbitrary shape
Select the line elements constituting the closed area and input the wind load. Wind load is applied as element beam load

Call

From the Main Menu select [Load] tap > [Type : Static Load] > [Lateral] group > [Wind Pressure] > [Nodal Wind Pressure]

Input

[Fig. Calculation of Nodal Loads]

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 X-Y 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.

Scale factor

Enter the increase/ decrease coefficient of wind load.

Velocity Pressure Name

Select the function for a velocity pressure function.
To add, modify or delete a velocity pressures, use the ... button.

Gust Factor

Input a external gust factor
To calculate the external gust factor automatically, use the ... button.

Base Nodes for Structure

Select or Input a nodes that support the wind load of the structure.
The nodal load substituted with the wind load is input at the corresponding point.

Structure

Set the shape or area & action point for wind load calculation. Please refer to the figure above for the calculation.

Automatic

- It provides 4 basic shapes.
- Use after modifying the geometry's dimensions.
- The bottom center of the selected structure is set the average value of the X, Y
coordinates and the highest Z level of the nodes selected in 'Base Nodes for Structure.

User Define

- Enter the loading area for the windward.
- Enter the centroid coordinate of the structure which the wind load is applied.
