Seismic Response of Multistory Buildings with Self-Centering Energy Dissipative Steel Braces
Bibliographic record
Abstract
This paper examines the seismic response of 2-, 4-, 8-, 12-, and 16-story steel framed buildings with self-centering energy dissipative (SCED) bracing members. The structures are assumed to be located in Los Angeles, California. Identical buildings equipped with buckling restrained braces (BRB) are also studied for comparison purposes. Incremental static analysis and nonlinear dynamic analysis under ground motion ensembles corresponding to three hazard levels were performed. The SCED frames generally experienced smaller peak story drifts, less damage concentration over the building height, and smaller residual lateral deformations compared to the BRB system. Higher floor acceleration peaks were observed in the SCED frames due to the sharper transitions between elastic and inelastic response assumed in the analysis. The study also indicated that higher design seismic loads may be needed for low-rise SCED and BRB frames in order to improve their collapse prevention performance.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
