Shaking table tests and numerical analysis on steel frame structure with various brace arrangements
Bibliographic record
Abstract
The steel frame-bracing system can increase the overall stiffness and lateral stiffness of the frame, significantly improving the seismic capacity of the structure. In this paper, shaking table tests were conducted on two 1/8 scaled steel frame structures, including a one-way brace arrangement scaled structure and a two-way brace arrangement scaled structure. A finite element (FE) model of the steel frame structure was established in Ansys, and its validity was verified against experimental results. Compared with experiments, an extended parameter analysis of the variable brace arrangement schemes of a multi-story space steel frame structure was conducted using the proposed FE model. The experimental and simulation results showed that the two-way brace arrangement in a steel frame structure significantly enhances the overall stiffness of the structure. The seismic performance of the brace arranged in a steel frame structure in the reverse wave direction is better than that of the brace arranged along the wave direction.
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 distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
