POWERFUL WINDOWS INTERFACE
The problem solving requirements of engineers are communicated to GT STRUDL through a standard Microsoft Windows menu-driven and graphical user interface In addition, GT STRUDL offers a structural engineering command interface as a compliment to its powerful interactive graphical modeling features. Engineers can retain and exercise control over all processing facilities to the extent required to meet engineer-defined needs, rather than merely inputting data to a predefined computer process.
GRAPHICAL MODEL CREATION
GTMenu is a graphical user interface within GT STRUDL that is designed for the generation, display, and changing of structural model data. Some of the major features of GTMenu are as follows:
Joints, members, finite elements, properties, constraints, releases, and loadings may be graphically created.

Input File Creation
A DATABASE DRIVEN SYSTEM , NOT A FILE DRIVEN SYSTEM
Unlike any other structural design and analysis system, GT STRUDL maintains a comprehensive structural database which contains problemdescription characteristics specified by the engineer, as well as results generated as a consequence of one or more analyses and/or design processes. The engineer may save, restore, display, update, correct, add, delete, activate, or inactivate any information in the problem database. This unique feature provides the engineer with significant time savings in the iterative structural analysis/design/ decision-making process wherein the computer stores, processes, and displays information upon request, while the engineer exercises decision-making responsibilities. Engineers can make requests for information "on the fly", rather than having to make decisions about what output they will want while defining the problem.
BROAD RANGE OF MEMBER AND FINITE ELEMENT TYPES FOR FRAME AND CONTINUUM MECHANICS
GT STRUDL contains a large library of member and finite element types consisting of 7 member types (constant or variable cross-section), over 100 conventional, isoparametric, and hybrid formulation finite element types, and many special transition elements including:
- Plane truss / frame / grid and space truss / frame members.
- Curved plane and space frame member element including internal pressure effects.
- Plate bending elements to model thin to moderately thick plates (3, 4, and 8 node triangles and quadrilaterals).
- 3-D solids (6 to 20 node triangular prisms and straight and curved edge bricks).
- Thin shell elements (3 and 4 node triangles and quadrilaterals with 5 or 6 degrees-of-freedom per node).
- Axisymmetric elements (4 to 8 node quadrilaterals) for modeling solids of revolution.
- Large library of special transition elements for plane stress, plane strain, Axisymmetric stress (4 to 8 node quadrilaterals) and 3-D solid (8 to 20 node bricks) problems.
- Special finite element for modeling shear walls and floor slabs where a rotational degree-of-freedom is provided about an axis normal to the element in order to allow coupling of member rotational degrees-of-freedom with the element (e.g., beam bending may now be coupled with a shear wall).
- Multilevel superelements (i.e., sub-structures defined from user specified collections of members, finite elements, and other superelements) may be defined for large and complex linear static analysis problems.
