1.1 RF-/LIMITS Add-on Module

The add-on modules RF-LIMITS (for RFEM) and LIMITS (for RSTAB) provide active structural engineers a comprehensive overview about the utilization of connecting elements or whether internal forces and deformations are met in the entire model.


In the following, the add-on modules of both main programs are described in one manual and are referred to as RF-/LIMITS.

Basically, RF/-LIMITS does not depend on any standard. However, you have the possibility to automatically include the specifications of the timber standards EN 1995 EN1995-1-1 and DIN 1052 DIN1052-2008 for the designs.

An extensive database offering connecting elements makes it easier to start working with the add-on module. It is also possible to extend the database by any other element. Especially for the design of connecting elements used in timber construction (for example joist hangers) the load influence factors kmod describing long-term effects can be determined conforming to standards.

RF-/LIMITS, like all other add-on modules, is integrated in the main programs RFEM and RSTAB: With the option to access the results of RFEM/RSTAB you can analyze modifications of the model or loading quickly in the add-on module. The results of the limit check can be documented as well in the printout report of RFEM and RSTAB.

Short description:
  • Checking internal forces on member ends, members and surfaces
  • Checking deformations of nodes
  • Checking forces and moments of nodal supports
  • Check of cross-section dimensions
  • User-defined design areas are taken into account
  • Interaction design for axial force, shear force and torsional moment
  • Database with DSTV connections according to EN 1993-1-8 EN1993-1-8

We hope you will enjoy working with RF-/LIMITS.
