Ground Motion Records for Mainshock-Aftershock Seismic Analysis

5,230,017 bytes of text data contain ground motion sequences used to study seismic dampers. This dataset supports research on the performance of self-centering rotational viscoelastic dampers with shape memory alloy strands. The data was generated for a specific publication in the Journal of Earthquake Engineering.

Use Cases

• Validating numerical models of self-centering rotational viscoelastic dampers using recorded ground motions.
• Assessing structural resilience under sequential seismic events based on mainshock-aftershock sequences.
• Comparing the performance of damping systems with shape memory alloy strands against conventional designs.
• Conducting nonlinear time-history analysis for structures subjected to multiple ground motions.

Strengths

• Dataset size is explicitly stated as 5,230,017 bytes across all sources.
• Released under a permissive CC0 1.0 public domain license, allowing unrestricted reuse.
• Directly linked to a peer-reviewed publication in the Journal of Earthquake Engineering, providing academic context.

Limitations

• Column names and data structure are unknown, limiting immediate usability.
• No row count is provided, making the dataset's record scale unclear.
• Documentation appears minimal, consisting only of the publication reference.
