The American Association of State Highway and Transportation Officials (AASHTO) has developed the “Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals” and later the “LRFD Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals” to govern the design of sign structures. The postprocessor includes on-screen graphing, review of analysis results, and design of base plates and splice plates. New allowable stresses (ASD)/forces (LRFD), combined stress ratio (CSR for ASD)/combined force ratio (CFR for LRFD) and especially the fatigue check (same for ASD and LRFD) are implemented in the new version. The analysis is based upon the 2001 w/later interims AASHTO “Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals” and 2015 w/later interims “LRFD Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals”.

The analysis module uses the general stiffness method to perform static analysis of space frames and includes automatic load calculation (dead, wind, and ice), stress analysis, and code checking. The preprocessor includes data entry/editing, mesh generation, and on-screen graphing, among other functions.
