Nodal 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.

Scale factor

Enter the increase/ decrease coefficient of wind load.

Wind Load Code

Select the standard for a calculation of wind pressure

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 and internal gust factor

To calculate the 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.
