Dynamic analyses in RFEM 6 and RSTAB 9 can be performed in several add-ons.
- The Modal Analysis add-on is the basic add-on, performing natural vibration analyses for member, surface, and solid models. It is a prerequisite for all other dynamic add-ons.
- The Response Spectrum Analysis add-on allows you to perform a seismic analysis using the multi-modal response spectrum analysis.
- The Time History Analysis add-on allows for a dynamic structural analysis of external excitations that can be defined as a function of time.
- The Pushover Analysis add-on allows you to determine the maximum nonlinear response of a structure to seismic loads.
- The Harmonic Response Analysis add-on is still under development.
This manual describes the dynamic analysis add-ons for RFEM 6 and RSTAB 9.
The "Steel Joints" add-on allows for the analysis of connections on the basis of an FE model. The design checks are carried out for various connection types for rolled and welded cross-sections. The input and result evaluation are completely integrated in the user interface of the structural FEA software RFEM.
This manual describes the Steel Joints add-on for RFEM 6.
In this tutorial, we would like to inform you about the essential features of the RFEM program. In the first part, a model was defined and a structural analysis carried out. Then the concrete and steel designs were performed in the following parts. This part now deals with the design of the steel connections according to EN 1993-1-8 with the CEN settings.
The Construction Stages Analysis (CSA) add-on allows you to represent the construction process of the model in the RFEM 6 program. In this way, you can add, remove, or adjust structural objects to the individual construction phases. Furthermore, you can use the add-on can to determine the sequence of the load application and the way how the load cases are combined within the construction stages.
The Torsional Warping (7 DOF) add-on allows you to consider the cross-section warping as an additional degree of freedom for a global calculation of members in RFEM and RSTAB. The input and result evaluation are completely integrated in the user interface of the structural FEA software RFEM and the frame & truss analysis software RSTAB.
This manual describes the Torsional Warping (7 DOF) add-on for the programs RFEM 6 and RSTAB 9.
The Geotechnical Analysis add-on allows for a finite element analysis of soil solids with the suitable material laws in RFEM 6. By integrating Geotechnical Analysis into the FEA software, the soil-structure interaction can be represented computationally completely in the overall model.
With the Geotechnical Analysis, it is possible to determine the stresses and deformations of a soil solid. The input and result evaluation are integrated in the user interface of the RFEM 6 program.
This manual describes the Geotechnical Analysis add-on for the RFEM 6 program.
This manual describes the topics of the webinar "Stability and Warping Torsion Analyses in RFEM 6 and RSTAB 9".
In the webinar, a stability analysis of a staircase tower is carried out. It explains when and why a warping torsion analysis with 7 degrees of freedom is necessary. Furthermore, special attention is given to how you can create and combine local imperfections in RFEM 6 and RSTAB 9.
In the manual, all steps are carried out in RFEM 6, but the same also applies to RSTAB 9.
In this tutorial, we would like to inform you about the essential features of the RFEM program. In the first part, a model was defined and a structural analysis carried out. Then the concrete and steel designs were performed out in the following parts. This part now guides you through the dynamic analysis of the model according to EN 1998-1 with the CEN settings.
