Economize with Efficiency.
Design better buildings with smart, safe, and cost-effective post-tensioned and reinforced concrete expertise.
As concrete structures become more complex with specialized demands, the use of post-tensioning is becoming more common. Post-tensioned and prestressed concrete building design is ever-changing and largely driven by safety, economy, and efficiency while meeting aggressive design demands. By combining PT design expertise and an intimate knowledge of 2D and 3D Finite Element Analysis software modeling and analysis tools, let PT-Structures elevate your post-tensioned and reinforced concrete design needs.
What We Do
Analysis & Design
Let us assist you with designated analysis and design services for post-tensioned concrete structures. This is our focus and expertise. We strive in delivering efficient and economical designs and rely on extensive experience in a diverse range of project and design applications.
Read MoreSoftware Technology
Our roots are in software application for the design and analysis of reinforced and post-tensioned concrete structures. So much relies on the accuracy of the models you create to aid in the design process. Gain confidence in your models. Tap into our extensive software modeling, troubleshooting, analysis and design know-how and get the job done right the first time with little model re-work and don't let it become the "black box."

The Printhouse Slab Retrofit New York, USA Existing RC Two-Way Slab Modeling This project required careful consideration of slab strength capacity of the as-built reinforcement placement due to several post-casting core penetrations placed in the slab. The existing structural elements, material properties, reinforcement and location was modeled and analyzed.
The Printhouse Slab Retrofit New York, USA Existing RC Two-Way Slab Evaluation The methodology for the evaluation required specifying critical location at core penetrations where the loss of capacity had occurred based on the size of the penetration and the reinforcement area that was lost at that location.
The Printhouse Slab Retrofit New York, USA Existing RC Two-Way Slab Results Critical sections were evaluated in both principal bending directions of the slab to determine capacity and demand at critical locations. Recommendations were given to strengthen the slab at regions where sections failed capacity due to loss of strength from the core penetrations.
3D Modeling of Post-TensioningWe convert your post-tensioned structural drawings or shop drawings into detailed 3D BIM models using Visicon. Each 3D tendon is accurately represented in its exact location and can be used to support construction coordination. We can deliver 3D tendons in Visicon VXF or Revit format.
BIM Coordination of PT DesignWe help you coordinate your post-tensioned design with other disciplines to ensure constructability issues are resolved early and don’t end up as costly RFIs on the jobsite. We combine a project’s various models that can be in Revit, ETABS, ADAPT, 3D DWG or IFC formats, run clash checks and prepare issue reports.
Model ValidationPTS can take your 3D project models and check them for compliance with other models on the project. For example, we check that the analysis, structural Revit, architectural Revit and Tekla fabrication models all represent the same design intent and within acceptable tolerances.
