Currently, when performing a spectral fatigue analysis, the SACS software generates a Fatigue Extract file, which can be opened in Precede as a PostVue database for fatigue results. From there, detailed fatigue information such as Design Life, Stress Range and Cycles, SCF, etc. can be extracted by manually selecting each joint, hotspot location, and load case.

However, these detailed results are not included in the listing file, making the Fatigue Extract file the only source for obtaining this information. For models containing a large number of joints, this process becomes inefficient and time-consuming, as every selection must be performed manually. It also increases the risk of transcription errors when transferring the data.

In contrast, deterministic fatigue analysis does not generate a Fatigue Extract file, but all the required fatigue results are available directly in the listing file, making them much easier to extract and process.

Is there a more efficient way to extract detailed results from spectral fatigue analysis while minimizing the risk of transcription errors? Alternatively, would it be possible for spectral fatigue analysis to provide all the data as below in the listing file, similar to deterministic fatigue analysis?

Several required fatigue data are listed as below, shall be applied for all joints in a model:

• Max fatigue damage and design life for all hotspots

• SCF

• Stress Range cycles report for all hotspot locations and all load cases
