Building Model for RFEM 6

The Building Model add-on allows you to efficiently analyze shear walls. The results of the shear wall are integrated using a result member. RFEM automatically calculates the relevant internal forces, such as shear stresses and deformations, and performs design checks according to the standard you select, for example, Eurocode 5, NDS, CSA 086 for timber, or Eurocode 2, ACI, and CSA A23.3 for concrete.

The results are clearly displayed in tables and graphical displays in the form of design ratios, with critical areas highlighted so that you can make specific adjustments. RFEM supports you in designing shear walls safely, efficiently, and according to your requirements.

In seismic analysis, the building model is used to list the identical tables as in the structural analysis, including the results of the spectral analysis. By integrating RFEM, you can apply horizontal actions such as earthquakes or wind loads directly to the building model and evaluate the response of the entire structural system.

By using the story modeling of rigid floor slabs, the masses of the structural system can be concentrated on the floors. This greatly reduces the mass degrees of freedom of the structural system. By considering the center of stiffness in the "Rigid Diaphragm" story modeling, it is also possible to more easily consider the random torsion required by the respective design standard.

For elements in building models, there are several modeling tools available:

• Vertical line
• Column
• Wall
• Beam
• Rectangular slab
• Polygonal slab
• Rectangular slab opening
• Polygonal slab opening

The Building Model add-on allows you to define the element at the base level (for example, a background layer) with the associated multiple element generation in space.
