Transmission tower software

ATADS is designed to provide the structural engineer with a set of tools for analysis and design of lattice transmission structures. ATADS is capable of analysis and design of three-dimensional structures using both Truss and Frame Analysis techniques.

• The number of configurations is limited by available memory. Each configuration typically contains a variation of the tower. Using configurations, differing combinations of legs and body extensions can all be contained in the same model.
• The number of joints, members, and load cases is each limited to 65000, typically far more than is actually needed.
• Tension only members and guy wires can be modeled.
• Translational and rotational restraints can be used that assist in the analysis of unstable structures.
• Wind areas and wind loads can be automatically calculated.
• Nonlinear member performance and Capacity Variation Analysis are included for advanced failure investigation analysis.
• Plotting options allow visualization of many model parameters.
• Hundreds of tests on the model can be performed to help detect common modeling issues. The results help to improve model accuracy.
• A member design tool is included to assist in optimizing a tower design. The tool can be based on either weight or cost.
• Models can be exported to several formats including bitmap, enhanced metafile, and both 2D and 3D International Graphics Standard for import into CAD systems.
