20 Basic Ground Motion Information for Seismic Fragility Analysis

Zhiyuan Gao published a dataset of 20 basic ground motion information records on figshare in May 2026. The data supports a comparative fragility analysis of prefabricated and cast-in-place frame structures using incremental dynamic analysis. The dataset is stored in an XLS file with a size of 9.5 KB.

Use Cases

• Compare seismic fragility curves based on a two-parameter damage model versus a traditional drift-based index.
• Characterize damage distribution along structural height using an energy-dissipation-based story damage weighting method.
• Validate finite element models of prefabricated columns and beam-column joints developed in SAP2000.
• Assess the impact of connection gaps and hysteretic degradation on structural collapse resistance under seismic loading.

Strengths

• Dataset is openly licensed under CC-BY-4.0.
• The underlying study validates finite element models against quasi-static test results.
• The description provides a detailed methodological context for the data's intended use.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 9.5 KB, indicating limited scope.
