A floating frame-type crashworthy device for protecting sea-crossing bridges subjected to ship collision

Data Description

This dataset supports the results presented in the manuscript submitted to Ships and Offshore Structures and contains only numerically generated data.

The data were obtained from a series of parametric numerical simulations conducted using the LS-DYNA finite element software, aiming to investigate the impact force characteristics and energy dissipation mechanisms during ship–structure collision scenarios. The simulations were performed under systematically varied parameters, including ship mass, impact velocity, and structural configuration, in order to evaluate their influence on collision response.

The dataset primarily consists of:

Time-history data of collision force, and

Energy-related response data, including kinetic energy, internal energy, and absorbed energy of structural components.

All data are organized into subfolders corresponding to different parametric working conditions. Each simulation case is uniquely identified according to its parameter combination, and the naming convention is documented to facilitate data interpretation and reuse.

This dataset is provided to:

Ensure the reproducibility of the numerical results reported in the associated paper;

Enable further comparative or parametric studies on ship–structure collision mechanics and impact-resistant structural design;

Serve as reference data for researchers using numerical methods in ship and offshore engineering.

No experimental, personal, or confidential data are included in this dataset.
