RFEM 6

The FEA software RFEM allows for modeling and structural analysis of general plate, shell, and member structures. It is also possible to analyze combined structures as well as solid elements and objects with contact properties.

This user manual describes the modeling, calculation, and result evaluation features related to the structural analysis.

Get Started With RFEM 6

RFEM and RSTAB are powerful programs helping structural engineers meet requirements in modern civil engineering. This short introduction to the software will guide you through the first steps and familiarize you with the most important functions.

Tutorial for RFEM 6 - US Version

In this tutorial, we would like to familiarize you with the essential features of the RFEM program. The first part shows you how to create the structural objects and loads, combine the loads, perform a structural analysis, check the results, and prepare the data for printing. For standards, the US codes are used.

CSA

With the Construction Stages Analysis (CSA) add-on, the construction process of structures can be considered in RFEM. Structural elements can be added, removed, and modified throughout the construction process. The application of loads and the combinatorics can also be considered across the construction stages.

This manual describes the Construction Stages Analysis (CSA) add-on for the program RFEM 6.

Dynamic analysis for RFEM 6

The dynamic analysis in RFEM 6 and RSTAB 9 is divided into several add-ons.

The 'Modal Analysis' add-on is the basic add-on that performs the natural vibration analysis 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 multimodal response spectrum analysis.

The add-ons 'Harmonic Frequency Response Analysis ',' Time History Analysis 'and' Pushover ' are still under development. You can find details about the planned content in the following chapter.

This manual describes the add-ons of the dynamic analysis for the programs RFEM 6 and RSTAB 9.

Concrete design for RFEM 6

It is possible to perform the ultimate limit state and serviceability limit state designs. Cross-section resistance, stability, and serviceability limit state designs can be performed. Input and result evaluation are completely integrated in the user interface of the FEM program RFEM and the framework program RSTAB.

This manual describes the Concrete Design add-on for the programs RFEM 6 and RSTAB 9, whereas RSTAB 9 only allows you to perform framework design.

Steel design for RFEM 6

The Steel Design add-on allows you to design steel members according to various design standards. Cross-section resistance, stability, and serviceability limit state designs can be performed. Input and result evaluation are completely integrated in the user interface of the FEM program RFEM and the framework program RSTAB.

This manual describes the Steel Design add-on for the programs RFEM 6 and RSTAB 9.

Timber design for RFEM 6

The Timber Design add-on allows you to design members made of timber according to various design standards. It is possible to perform designs of the cross -section resistance, stability and serviceability. Input and result evaluation are fully integrated in the user interface of the FEM program RFEM and the framework program RSTAB.

This manual describes the Timber Design add-on for the programs RFEM 6 and RSTAB 9.

Aluminum design for RFEM 6

The Aluminum Design add-on allows you to design aluminum members according to various design standards. Cross-section resistance, stability, and serviceability limit state designs can be performed. Input and result evaluation are completely integrated in the user interface of the FEA program RFEM and the framework program RSTAB.

This manual describes the Aluminum Design add-on for the programs RFEM 6 and RSTAB 9.

RFEM 5

The program RFEM allows you to enter and analyze structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells, members (beams), solids and contact elements.

RWIND

The RWIND program is a separate application that is used externally to determine load cases and wind loads for the RFEM or RSTAB models. The software uses a numerical CFD model to apply a fluid-mechanics simulation of the flow around objects in a wind tunnel.

RF-CONCRETE Surfaces 5

The RF-CONCRETE Surfaces add-on module performs ultimate and serviceability limit state designs of reinforced concrete surfaces according to various standards. The allowable maximum and minimum reinforcement ratios for the different types of structural components and a user-defined basic reinforcement are considered as well.

The manual also describes the module extensions RF-CONCRETE Deflect and RF-CONCRETE NL

RF-/CONCRETE Members 5/8

The RF-CONCRETE add-on module allows you to perform ultimate and serviceability limit state designs of reinforced concrete members according to various standards. Optionally, you can check whether the fire resistance design according to EN 1991-1-2 is fulfilled.

The manual also describes the module extension RF-CONCRETE NL.

RF-/STEEL EC3 5/8

The add-on modules RF-STEEL EC3 (for RFEM) and STEEL EC3 (for RSTAB) can carry out all characteristic ultimate limit state, stability, deformation, and fire resistance designs for steel members according to Eurocode 3. Country-specific regulations are taken into account by various National Annexes. This manual describes the add-on modules of the two main programs, summarily called "RF-/STEEL EC3".

The manual also addresses the module extensions RF-/STEEL Warping Torsion, RF-/STEEL Plasticity, and RF-/STEEL Cold-Formed Sections.

RF-/JOINTS 5/8

The add-on modules RF-JOINTS (for RFEM) and JOINTS (for RSTAB) combine the connection modules for member elements in a single user interface. Currently, the steel categories Column Base, Pinned, Rigid, Tower, DSTV, and Sikla, as well as the timber categories Steel to Timber and Timber to Timber are implemented. This manual describes the special features of each individual add-on module.

RF-/LIMITS 5/8

The RF-/LIMITS add‑on module analyses the load bearing capacity of members, member ends, nodes, nodal supports, and surfaces by means of a defined ultimate load capacity.

The extendable library covers timber fasteners (SIGHA, Sherpa, WÜRTH, Simpson StrongTie, KNAPP) as well as steel fasteners (standardised joints in steel structures according to EC 3, M‑connect).

RF-MOVE Surfaces 5

The RF-MOVE Surfaces add‑on module for RFEM creates load cases on the basis of various positions of moving loads such as vehicles on bridges.

In addition, it is possible to create an enveloping result combination.

BIM Interfaces

Dlubal Software supports the building information modeling by means of BIM (Building Information Modeling) using the BIM interfaces with Autodesk Revit and Tekla Structures. These interfaces are integrated into RFEM and RSTAB by default.
