GT-STRUDL-V29.1

STRUCTURAL DESIGN & ANALYSIS SOFTWARE

GT STRUDL is one of the most widely used Structural Design & Analysis software programs for Architectural - Engineering - Construction (AEC), CAE/CAD, utilities, offshore, industrial, nuclear and civil works. GT STRUDL is a fully integrated general-purpose structural information processing system capable of supplying an engineer with accurate and complete technical data for design decision making.
GT STRUDL completely integrates graphical modeling and result display, frame and finite static, dynamic, and nonlinear analysis, finite element analysis, structural frame design, graphical result display, and structural database management into a powerful menu driven information processing system. In over 30 years of use, GT STRUDL is one of the most widely accepted computer-aided engineering and design tools for the structural analyst and structural design engineer. GT STRUDL is used on a regular basis by thousands of engineers in over 30 countries.

The GTSES sparse equation solver, first implemented under the STIFFNESS ANALYSIS GTSES command in Version 29, has been implemented as a stand-alone program. When executed as such, the GTSES sparse equation solver is able to allocate all available virtual memory to its own execution process, thereby increasing the efficiency of the equation solution beyond the improvements already made by the STIFFNESS ANALYSIS GTSES command.

The STIFFNESS ANALYSIS GTSES command also stores the results of the analysis (joint displacements, member and finite element forces, finite element stresses and strains, reactions and resultant joint loads) in files in the current working directory, further increasing the size of static analysis models that can be solved and the efficiency with which they are solved.

• An example of a large model execution which completed in Version 29.1 but ran out of memory in Version 29 is shown below:

Number of Joints
40042
Number of Members
3055
Number of Elements
41332
Number of Loadings
50
Number of Loading Combinations
48
Average Bandwidth + Standard Deviation
584

Time to solve using GTSES for 240,252 degrees of freedom = 197 seconds

Total STIFFNESS ANALYSIS GTSES time = 767 seconds

• The AREA LOAD command has improved geometrical error detection and reporting. In addition, the total area and applied load are now printed as an additional verification tool.

• The output from the DESIGN SLAB command was modified to display a full listing of elements selected and used in the computation of the total moment acting on a cut section, for both the Wood & Armer and element force algorithms. The DESIGN SLAB command remains a prerelease feature in Version 29.1.
