Post-Tensioned Slab Modelling and Analysis in Revit

This tutorial explains the complete workflow for modelling, analysing and evaluating post-tensioned concrete slabs using SOFiSTiK Analysis + Design and SOFiSTiK Structural Desktop. The content covers prestressing system definition, tendon projection modelling, tendon station creation, tendon elevation control, finite element model generation and staged construction analysis. Participants learn how to configure prestressing properties, define tendon layouts, calculate tendon geometry and review tendon stresses and forces in reports, GRAPHIC and Viewer. The tutorial also explains automatic and user-defined tendon layouts as well as efficient modelling techniques for multiple tendons in Revit-based PT slab projects.
