Appendix ATraSiS#
TraSiS is an electronic implementation of the structural design procedures outlined in this Guide. Our newest upgrade includes additional features which greatly enhances the sign support structural design task. It replaces the Sign Design On-Line Software.
The software automates the design procedure and utilises the following inputs:
- sign size
- terrain cross-section
- use of frangible or non-frangible supports
- selection of wind region (in accordance with AS/NZS 1170.2) and
- foundation strength.
A detailed or summary output is provided, and includes:
- the type (CHS / RHS) and number of supports
- support section details (including variable wall thickness for different grades of steel)
- stiffener type, spacing and number of brackets, and
- footing details.
A significant enhancement to the previous version of the software is the addition of a clear zone module, which calculates clear zone distances based on the following variables:
- Annual Average Daily Traffic (AADT)
- horizontal alignment
- speed environment, and
- terrain cross-section.
The user can consequently specify frangible or non-frangible support, contingent upon the sign location.
