Live Load Library

The Live Load command is accessible from the Libraries pull-down menu, or selecting its respective icon. This screen shows the live load data in the library file. Note, the proper design code must be selected on the Project screen before setting up or modifying the corresponding live load library or the IRC design code to setup the IRC live load IRC_TruckLib.llb. The loads listed upon opening this command correspond to the currently loaded live load library file which was selected under the Libraries | Setup option. To load a different library file, use the Libraries | Setup option.

Click OK and return to the Live Load Library screen. The live load you just created will appear in the list under Items. Click Save to save the new live load in the currently loaded library file under the same file name, or click Save As to save it under a different file name. Once the live load library has been saved, click Close to exit this screen and return to the Main screen.

You can modify a live load by highlighting it and clicking Modify. In the screen that appears, make the necessary changes and click OK. To delete a live load, highlight it and click Delete.

Note: Changes made to the libraries will directly affect all previously linked data. Do not alter data unless absolutely necessary. As a general rule, do not delete items in the library unless you are sure that it has not been used or will not be used and any file.
