Load Combination page

Used to generate combinations of primary load cases for use in analysis and design.

Two types of load combinations are used:

Service Load Combination (i.e., allowable loads)
Ultimate Load Combination

You can create any number of load combinations.

Setting	Description
Load Combination Table	Select the code for specified load combinations or input your own: ASCE 7-05 ASCE 7-10 NBCC 05 Indian British Australian GB50009-2001 User Defined
Update Table	Default load combinations are saved in external data files (ACILOAD.INI files). Clicking the Update Table button saves any changes made to the associated table to the file as a default. Otherwise, any changes are saved in the active project file only.

Allowable Load Combination and Ultimate Load Combination tables	Each row in a table represents the ID for a different load combination. Index - The first column indicates the index of the load combination. toggle - Select the check boxes of the combination which you want to use. Load Type columns - Primary Load cases are assigned a load type, each of which is represented by a separate column in the load combination tables. Enter the load combination factor for a given load type in the cell. Tip: The cell with zero values appears in gray color where as with values other than zero it appears in blue. To add a new load combination to the table, add factors to the last (empty) row. Note: To add or change any combination from the default list (kept in an external .INI file) you need to click the Update Table button after making changes.
