Welcome to Dlubal Comunity 
, Thank you very much for your inquiries regarding precast prestressed concrete structures in RFEM6 .
The RFEM6 prestress concrete features in this area are in an early stage of development and require some manual work on the part of the user to complete the entire workflow you may require according to your demands. It is a solution based on finite element modeling of prestressing cables and strands. We offer the following features:
· Cross section and material library for prestressed cable, strands and multi-strands Tendons according to European and American Standards. Including presstress capacity limits and angular and wobble friction parameters.
· New type of member „Tendon“ that has only axial stiffness and it is mesh mapped automatically to master objects (concrete members or slabs) when it is physically inside of them. It means that Tendon members are rigidly connected to other members and transfer loads by geometry and connection.
· Posibility to use the RFEM6 line type catalogue as geometry layout (spline, parabola, nurbs, polyline) as a definition line for Tendon members. It is possible to make the Tendon layout parametric in RFEM6 using global parameters. We do offer the possibility to import .DXF templates to used as definition line for Tendon members.
· Loads need to be defined for now manually and applied as equivalent axial strain on Tendon members. You should apply load for short term losses in a separate load case as the long term losses.
· You can activate and deactivate Tendon elements in different construction stages in order to evaluate multistep prestressing and consider elastic shortening losses due to sequential prestressing.
· Standard design is not implemented yet, we do offer the possibility to develop serviciability stress checks by using Stress-Strain Add On and iterate with the Tendon geometry, cross section or prestress load to fullfill these stress checks.
