How do I determine the stiffness center of my system?


With the RFEM program, you can determine the center point of a system. This is explained in this FAQ .

However, the center point does not have to be necessarily confused with the stiffness center. It can be determined with the program SHAPE-THIN according to the theory of stiffening systems. The following webinar will also explain the practical application of the stiffness center in the seismic design.

To determine the center, it is also possible as a third and final option to consider the stiffness with a stiffness model in RFEM. In this series of technical articles, this will be explained in the following articles.
