# How can I consider eccentric load introduction?

As of the program version 5.19, you can directly consider the eccentric load introduction in RFEM by using the member loads (see Figure 01). The eccentric load introduction can be used for the "Force" load type.

As an alternative (for example, in RSTAB), you can also define a coupling by means of a rigid member to consider the external concentrated loads that act eccentrically on the member. The rigid member is to be connected perpendicularly to the corresponding member. The length of the rigid member corresponds to the amount of the eccentricity (see Figure 02).

As an alternative, you can enter the torsional moment due to the eccentric load introduction as external loading (also for eccentric member loads). Thus, the eccentric action would be taken into account and the definition of a rigid member would not be necessary (see Figure 03).
