Linear Multi-Step Static Form

When the Load Case Type is Multi-Step Static provide input in the following areas:

Load Case Name edit box. Use the name shown or type a new name in this edit box. It should be unique among all load cases of all types. Click the Set Def Name button to use a default name for the load case.
Notes Modify/Show button. Click this button to access the Load Case Notes form. Use the form to add notes to the model file specific to this load case.
Design button. Click this button to access the Design Load Type form. Choose Program Determined, or User Specified and then a design type from the drop-down list. Design load types are used in creating automatic design load combinations.
Stiffness to Use.

Loads Applied. Apply the loads from one or more load patterns or built-in acceleration loads. Usually multi-step load patterns, such as moving-load or wave-load cases, should be chosen, although standard non-stepped load pattern also may be applied.

Important: All loads specified will be added and applied in combination. A separate analysis output step will be created for each step of the specified multi-stepped load pattern. If more than one multi-stepped load pattern is included, the first output step will combine the loads of the first step of each of the load patterns, the second output step will combine the loads of the second step of each of the load patterns, and so on. Non-stepped load patterns will be combined at every output step. The total number of output steps will be equal to the largest number of steps in the specified load patterns.

- Load Type. 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. Choose the load name, or the global direction of ground acceleration, depending on the type of load.
- Scale Factor. 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.
- - Add button. After the Load Type, Load Name and Scale Factor have been specified, click the Add button to add the load.
  - Modify button.
  - 1. Highlight a load in the set of applied loads.
    2. Make any changes to the load type, load name, and scale factor at the top of the table.
    3. Click the Modify button.
  - Delete button.
  1. 1. Highlight the load to be deleted in the set of applied loads.
    2. Click the Delete button.
