This short video presents the most important new features of the past month.
In October 2022, the following functions have been implemented in RFEM 6 and RSTAB 9, among other things:
00:00 Shear joint for ribs
00:21 Separated imperfections according to Eurocode 2 and Eurocode 3
00:38 Member type "Surface Model"
01:05 Reduction of stiffness for "layers"

It is possible to save different model versions within a model by using the Save as Version function. In the Base Data of the model, the different model versions can be displayed in the History tab.
Using the "Beam Panel" thickness type, you can model timber panel elements in 3D space. You just specify the surface geometry and the timber panel elements are generated using an internal member-surface construct, including the simulation of the connection flexibility.
You have the option to perform the fire resistance design of surfaces using the reduced cross-section method. The reduction is applied over the surface thickness. It is possible to perform the design checks for all timber materials allowed for the design.
For cross-laminated timber, depending on the type of adhesive, you can select whether it is possible for individual carbonized layer parts to fall off, and whether you can expect increased charring in certain layer areas.

Among others, the following cross-laminated timber manufacturers are available in the layer structure library:
By importing a structure from the layer structure library, all relevant parameters are adopted automatically. The library is continually updated.
Main Program
The new generation of 3D FEA software is used for the structural analysis of members, surfaces, and solids.
Add-On
The Timber Design add-on performs the ultimate, serviceability, and fire resistance limit state design checks of timber members according to various standards.
Add-On
The Structure Stability add-on performs stability analysis of structures. It determines critical load factors and the corresponding stability modes.
Main Program
The modern 3D structural analysis and design program is suitable for the structural and dynamic analysis of beam structures as well as the design of concrete, steel, timber, and other materials.
Add-On
The Timber Design add-on performs the ultimate, serviceability, and fire resistance limit state design checks of timber members according to various standards.
Stand-Alone Program
Timber design of single-span and wide-span glulam beams according to Eurocode 5 or DIN 1052
Stand-Alone Program
Timber design of simple, continuous, and Gerber beams with or without cantilever according to Eurocode 5 or DIN 1052
Stand-Alone Program
Timber design of rectangular and circular columns according to Eurocode 5 or DIN 1052
Stand-Alone Program
Timber design of coupled purlins and continuous beams according to Eurocode 5 or DIN 1052
Stand-Alone Program
Timber design of three-hinged frames with finger joint connections according to Eurocode 5 or DIN 1052
Stand-Alone Program
Timber design of stiffening truss bracing according to Eurocode 5 or DIN 1052
Stand-Alone Program
Timber design of flat, monopitch, and duopitch roofs according to Eurocode 5
Add-On
The Nonlinear Material Behavior add-on allows you to consider material nonlinearities in RFEM for example, isotropic plastic, orthotropic plastic, isotropic damage).
Add-On
The Construction Stages Analysis (CSA) add-on allows for considering the construction process of structures (member, surface, and solid structures) in RFEM.
Add-On
The Time-Dependent Analysis (TDA) add-on allows you to consider the time-dependent material behavior of members. The long-term effects, such as creep, shrinkage, and aging, can influence the distribution of internal forces, depending on the structure.
Add-On
The Stress-Strain Analysis add-on performs general stress analysis by calculating the existing stresses and comparing them with the limit stresses.
Add-On
The Concrete Design add-on allows for various design checks according to international standards. You can design members, surfaces, and columns, as well as perform punching and deformation analyses.
Add-On
The Steel Design add-on performs the ultimate and serviceability limit state design checks of steel members according to various standards.
Add-On
The Masonry Design add-on for RFEM allows you to design masonry using the finite element method. It was developed as part of the research project titled DDMaS – Digitizing the Design of Masonry Structures. The material model represents the nonlinear behavior of the brick-mortar combination in the form of macro-modeling.
