Structural Modeling, Analysis, and Design Software

GT STRUDL is one of the most widely used, fully integrated, and adaptable structural analysis solutions in the world. The software has a proven track record in a variety of applications, such as nuclear and conventional power generation, onshore and offshore facilities, marine, civil engineering, and infrastructure. GT STRUDL offers engineers the accurate and complete technical data they need for cost-effective and efficient structural engineering and design decision-making. GT STRUDL is a market leader in its field for high quality results, proven reliability, and depth of technical support.


Track Record of Success

For almost 40 years, GT STRUDL has been one of the most widely accepted computeraided engineering and design tools for structural analysis and design. It is trusted and used globally by thousands of engineers to quickly and efficiently deliver accurate results.

Comprehensive Solution

GT STRUDL offers fully integrated and database-driven software for 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.

Nuclear Quality Assurance

Since 1983, the GT STRUDL Quality Assurance and Quality Control (QA/QC) program and procedures have been some of the industry most rigorous. They are in full compliance with applicable provisions of the U.S. NRC 10CFR21 and 10CFR50 Appendix B regulations. In addition, GT STRUDL QA procedures are in full conformance to the ASME NQA-1- 2008, including the 2009 Addenda Subpart 2.7 (NQA-1a-2009). The QA/QC program and procedures are routinely audited by independent auditors from nuclear industry corporate licensees several times each year. Auditors representing the Nuclear Procurement Issues Committee (NUPIC) and the Nuclear Industry Assessment Committee (NIAC) conduct audits every three years. Each version of GT STRUDL is thoroughly validated and verified (V&V) for its computational quality and performance with approximately 5,000 V&V test problems.


The linear and nonlinear static and dynamic analysis capabilities and high performance equation solvers of GT STRUDL are respected globally. Few programs possess its depth and breadth of functionality. GT STRUDL includes all the tools necessary to analyze a broad range of structural projects, from the simplest to the most complex, and can do so accurately and reliably in a fraction of the time that many other solutions require.

Steel Design

Structural engineers can perform steel member design and code-checking to follow a large variety of global steel design codes dating back to the 1960s. Examples of recent codes include the AISC 14th Edition, Eurocode 3 (EC3) 2005 Edition, ANSI/AISC N690 2012 Edition, ASME BPVC Subsection NF 2007 Edition, ISO 19902:2007(E) Edition, API RP 2A-WSD 21st Edition, and others. Steel design details are extensively documented, enabling the engineer to review the details of the code-checking procedures. With GT STRUDL, engineers can manage the steel member design and code-checking process through a large number of control options that enable engineers to cost-effectively deliver optimal designs.
