Do you work with the structural components consisting of slabs? In that case, you have to perform the shear force design with the requirements of punching shear design, for example, according to 6.4, EN 1992‑1‑1. In addition to floor slabs, you can also design foundation slabs in this way.
In the Ultimate Configuration for concrete design, you can define the punching design parameters for the selected nodes.
Do you want your structures to remain upright even in wind and snow? Then rely on the load wizards for plate and frame structures. You can now generate wind loads according to EN 1991‑1‑4 and snow loads according to EN 1991‑1‑3 (as well as other international standards). The load cases are generated depending on the roof shape.
Wind loads are also not a problem in your design. You can automatically generate wind loads as member loads or area loads (RFEM) on the following structural components:
The material library already includes the Canadian types of concrete and reinforcing steel available for design. However, you can always define other materials for the design according to CSA A23.3.
The units used for the reinforced concrete design according to CSA A23.3 are adjusted to the metric system by default.
There are load generators available for beam structures, creating snow loads according to ASCE/SEI 7-10. The load cases are generated depending on the roof shape. Another generator creates coating loads (ice). You can save recurring load combinations as templates.
The generated loads can be transferred easily to RFEM/RSTAB in order to superimpose other load cases. All module data is included in the RFEM/RSTAB printout report.
The report contents and the extent of the results can be selected specifically for the individual designs.
After generating the loads, you can check the results in clearly arranged tables. The output includes all information about the generated load cases and loads due to self-weight, wind load, and ice load. All loads are itemized in structural objects and equipment.
The RF-/TOWER Loading add-on module meets the requirements of EN 1991-1-4 / DIN EN 1993-3-1, DIN 1055-4, DIN 4131:1991-11, and DIN V 4131:2008-09. These standards include specifications of dead, wind, maintenance/technician and ice loads (ISO 12494 or DIN 1055-5), as well as variable loads. The standard specifications are preset or available in the libraries.

It is possible to generate individual load situations: You can set the wind pressure, wind direction, or ice loads manually, or import them from tables.
The calculated stresses and settlements are displayed in result windows. In addition, it is possible to evaluate the results graphically. The graphic displays the position and the layer arrangement of the soil samples to clarify the results.
The final result window shows the elastic foundation coefficients. Graphical evaluation is possible as well.
Elastic foundation coefficients are calculated according to the non-linear iterative method. The module determines elastic foundation coefficients for each individual element. They are dependent on the deformation.
The definition of soil layers is performed in a clearly arranged input window. An extensible library facilitates the selection of soil properties.
The elasticity can be defined either by the stiffness modulus or the modulus of elasticity and the Poisson's ratio. It is possible to define any number of soil layers. You can assign the layers to the building graphically or by entering the relevant coordinates.
Wind loads can be automatically generated as member loads or area loads on the following structural components (optional with internal pressure for open buildings):
