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. You can also enter one value and that is the load factor. In that case, the combination factor is set to 1.00.
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)
