In the Geotechnical Analysis add-on, the high-quality material model "Modified Hardening Soil Model" is available. This material model is suitable for a variety of soils and is able to appropriately represent the following properties of the real soil.
Stress dependence of soil stiffness
Load path dependence of soil stiffness
Plastic strains even before reaching the limit condition
Increasing shear resistance with increasing mesh refinement
Increasing yield strength with increasing stress until reaching the limit yield condition
Failure criterion according to Mohr-Coulomb
You can find more information about this material model and the definition of the input in RFEM in the corresponding chapter of the online manual for the Geotechnical Analysis add-on.
In the Construction Stages Analysis (CSA) add-on, you can use built-up cross-sections by means of what are known as phase sections. Parts of a cross-section of the type "Parametric - Massive II" can be activated or deactivated gradually throughout the construction stages.
In the Geotechnical Analysis add-on, the Hoek-Brown material model is available. The model shows linear-elastic ideal-plastic material behavior. Its nonlinear strength criterion is the most common failure criterion for stone and rocks.
You can enter the material parameters using
Rock parameters directly, or alternatively via
GSI classification.

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.
The Modal Analysis add-on provides you with the option to automatically increase the sought eigenvalues until a defined effective modal mass factor is reached. All translational directions activated as masses for the modal analysis are taken into account.
Thus, it is possible to easily calculate the required 90% of the effective modal mass for the response spectrum method.
The Timber Design add-on for RFEM 6 / RSTAB 9 is multi-purpose and combines a large number of additional elements. [*S16332764*]
