M. To apply a wind load

To apply a defined wind load to your structure, use the following procedure.

  1. Either:

    On the Loading ribbon tab, select the Load Items tool in the Loading Specifications group

    ヒント: This will add the load item to the currently selected load group selected in the program status bar.

    または

    In the Load & Definition dialog, select a primary load case in the Load Cases Details list and then click Add.

    The Add New Load Items dialog opens.
  2. Select the Wind Load > Wind Load tab.
    注記: If you have not previously added a wind load definition to the model, this tab is inactive. Refer to M. To add a wind load definition for details.
  3. In the Select Type drop-down list, select the wind load definition for this load case.
  4. Select the Exposed Surface and Direction of the load and then type the load Factor value.
  5. (オプション) If the wind load definition is for a SNiP code, specify the additional SNiP Parameters:
    1. Select the configuration from the drop-down list.
    2. Type the wind pressure coefficient.
  6. Specify the range of values over which the load applies. Type the along the global axis of how the wind load acts.

    Depending on the arrangement of walls, you may need to sub-divide the wind load application into multiple entries with overlapping ranges. The program may not automatically recognize all open-ended wind panels. Refer to オープンエンドパネルの識別の制御 for additional details.

    ヒント: Alternately, you may specify member lists or group definitions using the command input.
  7. (オプション) Check the Open Structure option for truss, lattice, or other open structure types. This will apply the load only to the projected area of the members and joints, not to the bounded area of members or surfaces.
  8. Click Add.
The program will automatically calculate the joint loads for structure that lies within the specified range. Selecting the wind load item in the Load & Definition dialog will highlight the loading members. The calculated surface exposure and the tributary areas will also be displayed for closed structures.
Review the wind panels for each wind load case to ensure that the intended areas are loaded. The panels are color coded to identify unique tributary areas.
