tnxTower Overview
Complete Standards Support
The program analyzes towers using the ANSI/TIA-222-I Standard or any of the previous TIA/EIA Standards back to RS-222 (1959). Steel design is checked using the TIA/EIA Standards, AISC ASD 9th Edition or the AISC LRFD Specifications, as applicable. The Canadian Standard CSA S37-01 is available as well.
Powerful Analysis & Design
tnxTower’s rapid model creation tools, 3-D frame-truss models and automatic wind force and ice loading generation capabilities are just a few of the features that make this industry-standard software the premier choice for all types of communication towers.
Top-notch Graphical Presentation
Graphical display of tower geometry, appurtenances, internal forces, stresses and displacements are created automatically.
Extensive graphics plots include material take-off, shear-moment, leg compression, displacement, twist, feed line, guy anchor and stress plots. tnxTower contains unique features such as True Cable behavior, hog rod take-up, foundation stiffness and much more.
tnxTower is a general-purpose modeling, analysis, and design program created specifically for communications towers.
The following Standards are currently implemented:
RS-222, RS-222-A, RS-222-B, EIA-222-C, EIA-222-D, EIA-222-E, TIA/EIA-222-F, ANSI/TIA-222-G (including TIA-222-G-1 and TIA-222-G-2), ANSI/TIA-222-H, ANSI/TIA-222-I, and CSA S37-01.
