TECHNICAL FEATURE // HSE SOFTWARE: FATIGUE LIMITE STATE
The HSE – Highway Sign Structural Engineering software includes the fatigue limit state.
The HSE software allows for Fatigue verification according to chapter 11 of AASHTO LTS-13 (ASD) and AASHTO LTS-15 (LRFD) and Stress verification according to the Constant Amplitude Fatigue Threshold (CAFT).
The CAFT (Constant Amplitude Fatigue Threshold) for infinite life for the different fatigue detail categories are found in AASHTO LTS-13 (ASD) Table 11.9.3.1-1 and AASHTO LTS-15 (LRFD) Table 11.9.3.1-1.
To enhance productivity and ease of use of the HSE software, HSE users can efficiently set and edit all required fatigue parameters for a structure allowing to consider all applicable fatigue loads such as Galloping, Natural Wind Gust, or Truck-Induced Gust.

Variable anchorage slip in wood shearwalls
To enhance productivity of GSE Timber software’ users, the Anchorage Elongation Method can be defined as variable (tension only) and variable (tension and compression). The anchorage slip is calculated at each iteration according to the tension efforts at the anchorage locations.
Fatigue limit state
HSE users can efficiently set and edit all required fatigue parameters for the structure allowing to consider all applicable fatigue loads such as Galloping, Natural Wind Gust, or Truck-Induced Gust.
Live load reduction
The live load reduction is available for the GSE steel, concrete, aluminum, and wood modules. The live load reduction will be applied to the columns of the structure.
Live loads can be automatically reduced according to the selected method. The software computes the live load reduction factor (LLRF) that will reduce the effective axial compression force in columns.
Fire resistance of wood elements
The resistance limit states, under fire conditions, are calculated for large cross-section wood elements. To improve the productivity of GSE users, the elements cross-sections are automatically reduced during the limit state checks.
