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. 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 a 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.

By standard there are three load combinations generated. ULS 6.10a, ULS 6.10b and SLS
