Main Program RFEM: Precise Structural Engineering of Buildings
Recommended Add-on Products for Building Models
Geotechnical Analysis
In RFEM, the Geotechnical Analysis add-on uses properties from soil samples to determine the soil body to be analyzed. The accurate determination of soil conditions significantly affects the quality of the structural analysis of buildings.
Response Spectrum Analysis
The Response Spectrum Analysis add-on performs seismic analysis using multi-modal response spectrum analysis. The spectra required for this can be created in compliance with the standards or can be user-defined. The equivalent static forces are generated from them. The add-on includes an extensive library of accelerograms from seismic zones that can be used to generate the response spectra.
Construction Stages
The Construction Stages Analysis (CSA) add-on allows for considering the construction process of structures (member, surface, and solid structures) in RFEM.
Support and Learning
We provide professional support and many services in order to help you with finding a quick and efficient solution for your projects.

Suzhou Olympic Sports Center
Suzhou is a well-known garden city in China, where nine of its classical gardens are listed as UNESCO World Heritage Sites. The project and design of Suzhou Olympic Sports Centre are based on Chinese gardens in order to create a lively and publicly accessible sports park. The stadium roof is currently the largest single-layer cable network structure with membrane roofing in East Asia.

"Terma Bania" Building Extension and Renovation in Białka Tatrzańska
An additional extension, which includes lounge and restaurant areas, was added to the existing "Terma Bania" aquapark. The building was designed as a reinforced concrete monolithic slab-column structure.

Hotel Intercontinental in Davos, Switzerland
In December 2013, a hotel with extraordinary architecture opened in Davos, Switzerland. The building has the shape of a “Golden Egg” and is situated on a mountainside.
The hotel is elliptical in shape with all corners rounded, and is constructed with reinforced concrete.

The coefficient θ is calculated as follows:$$\mathrm\theta\;=\;\frac{\displaystyle{\mathrm P}_\mathrm{tot}\;\cdot\;{\mathrm d}_\mathrm r}{{\mathrm V}_\mathrm{tot}\;\cdot\;\mathrm h}\;$$

The building model is calculated in two phases:
- Global 3D calculation of the global model, where the slabs are modeled as a rigid plane (diaphragm) or as a bending plate
- Local 2D calculation of the individual floors
After the calculation, the results of the columns and walls from the 3D calculation and the results of the slabs from the 2D calculation are combined in a single model. This means that there is no need to switch between the 3D model and the individual 2D models of the slabs. The user only works with one model, saves valuable time, and avoids possible errors in the manual data exchange between the 3D model and the individual 2D ceiling models.
The vertical surfaces in the model can be divided into shear walls and opening lintels. The program automatically generates internal result members from these wall objects, so they can be designed as members according to any standard in the Concrete Design add-on.
Several modeling tools are available for elements in building models:
- Vertical line
- Column
- Wall
- Beam
- Rectangular floor
- Polygonal floor
- Rectangular floor opening
- Polygonal floor opening
This feature allows you to define the element on the ground plane (for example, with a background layer) with the associated multiple element creation in space.
Using the "Load Transfer Only" story type, you can consider slabs without stiffness effect in and out of the plane in the Building Model add-on. This element type collects the loads on the slab and transfers them to the supporting elements of a 3D model. Thus, you can simulate secondary components, such as grillage and similar load distribution elements, without any further effect in the 3D model.
Use the "Independent mesh preferred" option in the FE mesh settings to create an independent FE mesh for the integrated objects. This allows you to generate a significantly more detailed and precise FE mesh for individual objects that are integrated into one another.
