This package contains the modules required to perform any dynamic deterministic, time history, or spectral fatigue analysis. It also includes modules for general dynamic and seismic analyses. SACS Fatigue Ultimate contains SACS Fatigue, Interactive Fatigue, Dynamic Response, and Wave Response. It requires the use of the SACS Offshore Structure, Offshore Structure Advanced, or Offshore Structure Ultimate.

– Supports full 3D geometry and section properties
–  Allows SACS model files to be ported directly to a PDMS macro file, which creates the 3D model in PDMS
– Supports PDMS section libraries in addition to creating PDMS sections defined in the SACS model
– Logging functionality
– ISM Export to ProSteel and other steel detailing systems
– Integrated with ProjectWise for sharing all projects files across multiple sites

– Spectral, time history, and deterministic fatigue analysis
– Cyclic stress range calculation procedures include wave search,
curve fit, and interpolation
– SCF calculations recommended by API (including 21st edition
supplements), HSE, DNV, DS449, and Norsok Codes
– Automatic redesign
– API (including 21st edition supplements), ISO 19902, AWS, HSE, and Norsok thickness dependent recommended S-N curves
– Multiple run damage accumulation
– Pierson-Moskowitz, JONSWAP, Ochi-Hubble double peak, simplified double peak, and user-defined spectra
– Automated or user-specified connection details
– Pile fatigue analysis
– Creates wave spectra from scatter diagram
– Uses Paris equation to predict crack growth rate due to cyclic stresses
– Load path dependent joint classifications
– Includes wave spreading effects
– Reservoir (rain flow) cycle counting method

– Shows the 3D view of the connection and allows braces to be selected with the mouse
– Reads connection defaults when joint and/or brace is/are selected, thus eliminating the need to calculate and display SCFs before viewing capacity or modifying properties
– Recognizes all SCF and S-N options available in the batch program
– Allows SCF theory to be changed for any type of connection, including inline connections and connections with user-defined SCFs
– Reports have been expanded and reworked to make them easier to read
– Reports and plots can be displayed on the screen and/or saved to a file
– Automatic redesign
