In RF- / DYNAM Pro I have the possibility to select a conversion type for the mass. What do the different options mean and what are the differences?

Answer

This setting defines how the defined loads in RFEM / RSTAB are handled in the dynamics module, since these must first be transformed in bulk.

Z-load components: When this option is selected, only those masses that act in the Z direction are considered. This includes the positive as well as the negative direction. This option is the default because it is desired in most applications. Loads, such as earth pressure, defined in a horizontal direction are not taken into account.

Z load shares (in the direction of gravity): Here the loads are considered only in positive Z-axis. If you want to use this option, you should check in which direction the Z-axis was defined. With this option, it does not matter in which direction you set the dead weight in a load case.

Full load as mass: This option converts all loads into masses, both horizontal and vertical.
