Tower Design Software Gains New Owner

November 1, 2010

RISATower, a product of RISA Technologies, has been acquired by Tower Numerics, a developer of structural design software for communication and wind turbine towers.

“We are fully committed to serving the tower industry,” said Peter Chojnacki, founder of Tower Numerics and former employee of RISA Technologies. “As part of that commitment, we will accelerate the development of RISATower (now TnxTower) and introduce additional products and services of interest to tower design professionals.”

TnxTower is used as a tower structural design tool created specifically for the telecommunications industry, automating much of the tower analysis and design required by the TIA/EIA 222 Standard. TnxTower analyzes towers using the ANSI/TIA-222-G (2005) standard or any of the previous TIA/EIA standards back to RS-222 (1959). Steel design is checked using the AISC ASD 9th Edition or the AISC LRFD specifications.

“RISA Technologies is committed to working with Peter and Tower Numerics to ensure all RISATower clients enjoy a smooth transition over to TnxTower,” said Bruce Bates, president of RISA Technologies. “We’re excited for Peter as he begins this new venture, and we look forward to an ongoing relationship with Tower Numerics.”

TnxTower analyzes and designs three- and four-sided guyed and self-supporting towers and either round or tapered groundmounted poles with or without guy wires. TnxTower features true cable behavior, hog rod take-up and foundation stiffness. TnxTower may export complete model files to RISA-3D for added analysis and design flexibility.

The program analyzes towers using the TIA-222-G (including Addendum No. 1) 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.
