The data specified in RFEM concerning material, loads and load combinations must be entered in accordance with the design concept described in the Indian standard IS 800. The RFEM library already contains appropriate materials for
IS 800. 

In RF-STEEL IS, you select first the members and sets of members you want to design, and then the load case, groups and combinations.

En supplément, le module additionnel RF-COMBI permet une création automatique des combinaisons de charge correspondantes, conformément à la norme indienne. Il est aussi cependant possible de générer toutes les combinaisons manuellement dans RFEM. Dans RF-STEEL IS, d'abord, vous sélectionnez les barres et les ensembles de barres, que vous souhaitez concevoir et apres les le cas de charge, groupes et combinaisons. 

During the next steps, you can adjust the preset settings for lateral intermediate supports and effective lengths. In case continuous members are used, it is possible to define individual support conditions and eccentricities for each intermediate node of the single members. 

In the program's background, a special FEA tool determines the critical loads and moments required for the stability analysis.

The first results table shows the maximum design ratios with the corresponding design for each designed load case, group or combination.

The following tables show all detailed results sorted by specific subjects in extendable tree menus. Moreover, it is possible to display all intermediate results for each location along the members. In this way, you can easily retrace how the individual designs have been carried out by the module.

The entire module data is part of the RFEM printout report. The contents for the report and the extent of the output data can be selected specifically for the individual designs.
