Structural Analysis and Design Modeling Software


For nearly 40 years, GT STRUDL has offered structural engineers a complete design solution, and with the addition of GT STRUDL’s 2015 release, we’ve now incorporated 3D CAD modeling and 64-bit high-performance computation solvers into all versions. Our structural analysis software is a high-quality, fully integrated, and database-driven system for comprehensive frame and finite element analysis, and steel and reinforced concrete design.

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 solutions. The new CAD Modeler GUI uses an AutoCAD®-based environment that allows engineers to instantly see the analysis and design results.

Plays Well with Other Software

GT STRUDL can import and export models via CIS/2. This allows structural data-rich models created outside of GT STRUDL to fully leverage the power of GT STRUDL. External packages can benefit from the advanced power and benefits that GT STRUDL offers.

Start Smart

You don’t need to build from scratch. We have pre-populated common structural analysis templates that are up to code and accurate. Customize these templates to save time and work efficiently and safely.

Verified to Work

Each version of GT STRUDL is validated and verified (V&V) for its computational quality and performance by more than 350 Base Verification test problems that are documented in the 4-volume Base Verification Manual, and by approximately 4,700 additional general V&V test problems, for a total of approximately 5,000 V&V test problems.

Feature-rich Integration

GT STRUDL is a fully integrated and database driven software system for general frame and finite element analysis and comprehensive structural engineering design. GT STRUDL has more than 10 functional areas that operate seamlessly with one another. Combined with amazingly fast computational speed (now 64-bit in the 2015 release), this provides virtually unlimited power and flexibility for projects of any size or complexity.

User Documentation and Support

While other solutions may only allow you to search for training and help online, Intergraph offers a full support staff to take your calls and personally answer emails. GT STRUDL documentation details functionality, application of cutting-edge technologies, implementation of structural mechanics, theoretical formulations, and design code specifications. This gives the structural engineer a full and clear understanding of GT STRUDL’s features and capabilities.

Optimized Steel Design

GT STRUDL steel design provides the structural engineer with the ability to perform steel member design and code checking pursuant to a large variety of global steel design codes dating back to the 1960s, which can be controlled by user specified parameters, absolute and relative geometric constraints, member size smoothing strategies, automatic analysis/design iterations, and many more design control options.

Intuitive Base Plate Wizard

Complex steel base plate modeling, linear and nonlinear analysis, and performance evaluations can be performed using an easy-to-use and full featured graphical interface. Users can model base plate criteria including holes; notches; tabs; anchors; attachments; stiffeners; bearing surface data; and boundary conditions representing shear lugs, edge welds, etc.

Easier Reinforced Concrete Design

Design beams, columns, one-way slabs, shear walls, and two-way flat plate and flat slab structures per ACI 318. With special member, floor slab, and wall panel automatic generation capabilities, even complex reinforced concrete building structures are easily modeled. GT STRUDL also provides detailed quantity take-offs based on design results.

Offshore Jacket and Pile Analysis

Analyze and model environmental loadings, such as wind loads, cyclic wave loads, current loads, buoyancy loads, launching and lifting loads, and seismic loads that are applied to offshore structures like fixed jacket structures, cable-stayed and tension-leg semi-submersible structures, and other rigid floating structures.

The following types of analysis can be performed: linear and nonlinear, jacket launch, stability and upending, fatigue checking using Power Spectral Density, Discreet Probability, and Deterministic methods, stress concentration factor calculations, punching shear checks, nonlinear pile-structure interaction, and code checking by the ISO 19902:2007(E),API RP 2A-WSD 21st and 20th Editions, RP 2A-LRFD 1st Edition, RP 2A 17th and 15th Editions, and NPD 1983 design code specifications.
