Is it possible to design also flat slabs in RF-TENDON and RF-TENDON Design?

Answer

The add-on module is designed for a pre-tensioned or post-tensioned bond. The templates for the tendon geometry are based on parabolic diagrams. This means that the modules are not designed explicitly for the design of flat slabs.

Possible Figure:

The geometric distribution for the free tendon position cannot be determined automatically by the add-on modules. However, it is possible to use a user-defined tendon profile as a basis. A prestress without bond could be set by adjusting the friction coefficient.

The deformation analysis can not be performed in the RF-TENDON and RF-TENDON Design add-on modules. However, a deformation analysis on the side of RFEM in conjunction with RF-CONCRETE NL or RF-CONCRETE Deflect could be performed by applying the equivalent prestress loads. The equivalent prestress loads are exported without the influence of long-term losses and would have to be reduced by a factor corresponding to these losses in RFEM.
