'''No.'''

This number is automatically generated. You can not change this number.


'''Description'''

Free text space to describe the load combination


'''Type'''

The type of load (ULS - ultimate limit state, ULS- fire, SLS-serviceability limit state, quasi permanent). Dependent on the type of combination, standard values for the combination factors (psi) and the load factor (gamma) are offered according to the Eurocode. But these values can be adapted.


'''Columns with load cases'''

For all the load cases, columns are created. In that way, a table appears in which all the combinations are shown. Every cell contains 2 values in the syntax : combination factor x load factor.


When you click on the cell the following dialog box appears. Here you can adapt both values.

For the combination factor and the load factor combo-boxes are offered including the standard values from which you can choose. You can also insert an own value. This gives a lot of freedom. If you for instance take one of the values as zero, the product of the two values obviously is zero as well. In that case the cell is showed 'empty'. This is only to make things clear.


Standard there are three load combinations generated. (ULS (6.10a), ULS (6.10b) and SLS)
===Sequence load combinations===
With a click on the right mouse button, the context menu shown below is opened. With these functions you can easily adapt the sequence of the load cases and/or insert load cases.

'''Delete'''

The load combination is deleted.


'''Copy'''

The load combination is copied.


'''Move up/ move down'''

A load combination can be moved up and down a line.


'''Copy ULS combination to SLS'''

Every load combination of the type ULS will be copied as type SLS. The load factors are set to 1.
