文摘
- •
An innovative block partition and equivalence method of the wave scatter diagram is developed for fatigue assessment.
- •
The equivalent wave period is calculated via the spectral moment formula based on the weighted averaging principle.
- •
The significant wave height is determined by inversing the wave spectrum integral with a modified equivalent wave energy.
- •
The developed method is robust, computationally affordable, and accurate within engineering expectations.
