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. Damping ranges from 1% to 5% and Damage severity ranges from 25% to 75% member stiffness degradation of a single horizontal X-brace. 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.
