Wave-Heading-Dependent Directional Transmissibility Datasets for Localized Damage Identification in Offshore Jacket Structures

This repository contains the numerical simulation data, processed response datasets, and Python-based post-processing scripts associated with the study:

“Wave-Heading-Dependent Directional Transmissibility for Localized Damage Identification in Offshore Jacket Structures.”

The dataset supports investigation of directional dynamic-response behavior and transmissibility-based damage identification in a fixed offshore jacket structure subjected to hydrodynamic loading under varying wave-heading conditions.

The repository includes:

* raw Abaqus numerical analysis output files;
* extracted acceleration response histories for all investigated wave headings and structural conditions;
* processed FFT and PSD datasets;
* directional transmissibility datasets;
* Python scripts used for automated response extraction and post-processing;
* representative hydrodynamic loading histories;
* and publication figures associated with the study.

The numerical investigations consider both undamaged and damaged offshore jacket structural conditions, where localized structural degradation is simulated through stiffness reduction of a single horizontal X-brace member. Wave headings ranging from 0∘ to 90∘ at 15∘ increments are included.

The repository is intended to support reproducibility, further analysis, and future development of offshore structural health monitoring methodologies based on directional dynamic-response characteristics under operational environmental loading conditions.
