Load Case Data Form - Linear Static

When the Load Case Type is Linear Static , provide input in the following areas:

Note: Please refer to the Load Case Data Form topic for information related to the Load Case Name edit box, the Load Case Type and Load Case Subtype drop-down lists, and the Notes Modify/Show and Design buttons.

• P-Delta/Nonlinear Stiffness options.

• • Use Preset P-Delta Settings  option. Click the Modify/Show button to access the Preset P-Delta Options form. Use that form to set the P-Delta analysis parameters.

  • Use Nonlinear Case (Loads at End of Case NOT Included) option. Choose to start at the end of a nonlinear load case. Use the drop-down list to select the load case.

• Loads Applied. Apply the loads from one or more load patterns or built-in acceleration loads. Usually, only one load pattern or acceleration load is used.  Begin using this area of the form by clicking the Add button.

Important: All loads specified will be added and applied in combination. Only a single response will be calculated. Create different load cases to obtain separate responses to separate loads.

• • Load Type drop-down list. Choose whether the load to be applied is a load pattern or a built-in acceleration load. See Applying Acceleration Loads for more information.

  • Load Name  drop-down list. Choose the load pattern name, or the global direction of ground acceleration, depending on the type of load.

  • Scale Factor edit box. Enter a scale factor that multiplies the load before adding it to other loads applied. For acceleration loads, the scale factor has units of acceleration, and should be consistent with the length units currently in use. For load patterns, the scale factor is unitless.

  • • Delete button.

    1. 1. Highlight the load pattern to be deleted in the set of applied loads.

       2. Click the Delete button.
