We provide hints and tips to help you get started with the RFEM program.
RFEM 6 | FEM Structural Analysis Software
RFEM | Powerful, Easy, and Intuitive
First Steps with RFEM
The structural analysis program RFEM 6 provides structural engineers with a 3D FEA program that meets all requirements in modern civil engineering. Efficient data input and intuitive handling facilitate the modeling of simple and complex structures.
The structural analysis program RFEM is the basis of a modular software system. The basic program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.
RFEM calculates deformations, internal forces, stresses, support forces, and soil contact stresses. Load wizards facilitate the application of wind and snow loads, and other load. With the help of add-ons, you can carry out additional analyses and designs according to various standards (for example, in reinforced concrete, steel, and timber structures).
The modular software concept allows you to compile a program package tailored to your individual needs. It is possible to upgrade the program at any time.
Documentation
Design check formulas used in the design (including a reference to the used equation from the standard) are clearly displayed. As a result, there is no "black box" calculation. All input data and results can be documented in the multilingual printout report. The scope of the output can be adjusted individually.

Advantages of Spatial FEA Model
"The spatial FEA model offered very good options to analyze and design the load-bearing behavior of a special complex structure in a verifiable way. Due to the extremely high safety requirements concerning the most famous landmark of Germany, the Brandenburg Gate, it was necessary to mount the support structure in two stages. The specific mounting situations could be modeled very well in RFEM."

X-Brace Effective Lengths According to AISC 360-16 in RFEM 6
Defining the appropriate effective length is crucial to obtain the correct member design capacity. For X-bracing that is connected at the center, the engineers often wonder if the full end-to-end length of the member shall be used or using half of the length to where the members are connected is sufficient.
This article outlines the recommendations given by the AISC and provides an example on how to specify the effective length of the X-braces in RFEM.
