GT STRUDL® is structural engineering software offering a complete design solution, including 3D CAD modeling and 64-bit high-performance computation solvers into all versions. GT STRUDL includes all the tools necessary to analyze a broad range of structural engineering and finite element analysis problems, including linear and nonlinear static and dynamic analysis, and can do so accurately in a fraction of the time of most other structural design software.


Comprehensive Solution

GT STRUDL is an easy to use and flexible interoperable and database-driven
solution for beam and general finite element analysis and comprehensive structural engineering design. The solution includes 10 functional areas that operate seamlessly with one another. Combined with amazingly fast computational speed, GT STRUDL provides virtually unlimited power and flexibility for projects of any size or complexity.


GT STRUDL is natively interoperable with Intergraph Smart® solutions, CAESAR II and CADWorx® Structure. This enables structural data-rich models created outside of GT STRUDL to fully leverage the power of GT STRUDL. It is also interoperable with third- party solutions through CIS/2 and GTI files. Reduce duplication of effort to save time and ensure data accuracy.

Quality Assurance

Since 1983, the GT STRUDL QA/QC program has been in full compliance with applicable provisions of the U.S. NRC’s 10CFR21 and 10CFR50 Appendix B regulations. In addition, GT STRUDL QA procedures conform to the ASME NQA 1- 2008, including the 2009 Addenda Subpart 2.7 (NQA-1a-2009). This means that every release of GT STRUDL earns the trust of structural engineers by providing accurate analysis results.
