What's New in Version 5.1
The latest release of RISATower adds flexibility of feed line definition that helps produce better optimized and more efficient designs. User-controlled variable wind pressure application allows to fine tune the load application on a section-by-section basis. New databases for structural component and bolt materials, implementation of Addendum No. 1 to TIA-222-G, and numerous fixes and GUI enhancements are also included.
Overview

Designed specifically for the telecommunications industry, RISATower, formerly ERITower, automates much of the tower analysis and design required by the TIA/EIA 222 Standard.

RISATower can analyze and design 3- and 4-sided guyed towers, 3- and 4-sided self-supporting towers and either round or tapered ground mounted poles with or without guys.

The program analyzes towers using the 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.

Linear and non-linear (P-delta) analyses can be used in determining displacements and forces in the structure. Wind pressures and forces are automatically calculated.

Extensive graphics plots include material take-off, shear-moment, leg compression, displacement, twist, feed line, guy anchor and stress plots.

RISATower contains unique features such as True Cable behavior, hog rod take-up, foundation stiffness and much more.
