If additional masses act in addition to the static loads, you can consider them using the Mass load type. In RFEM, this is possible for nodal, member, line, and surface loads, and in RSTAB, it is only possible for nodal and member loads. You can add the additional masses in the respective load cases.
Additional Nodal Masses
You can define either a "mass" M or the "individual mass components" that are effective at the node in the X, Y, and Z directions. In the latter case, it is also possible to specify the "moment of inertia" IX, IY, and IZ in order to model more complex mass points. For example, the rotational movements of a machine can be approximately taken into account.
Additional Line Masses (RFEM only)
You can define either a line mass M or the "individual mass components" that are effective at the node in the X, Y, and Z directions.
Line masses are given in [t per unit of length].
Tip
You can change the unit in the Units and Decimal Places dialog box. To do this, click the
button at the bottom of the dialog box.
Additional Member Masses
You can define a member mass M or the "individual mass components" that are effective at the node in the X, Y, and Z directions. Member masses are given in [t per unit of length].
Additional Surface Masses (RFEM only)
Specify a surface mass M or the "individual mass components" that are effective on the surface in the X, Y, and Z directions. Surface masses are given in [t per area unit].
