Seismic Analysis of Unreinforced Masonry Structures with Plan Irregularities
Bibliographic record
Abstract
Unreinforced masonry (URM) is inherently vulnerable to seismic forces due to its minimal ability to resist tensile forces.Typical structural design features in URM buildings such as torsional irregularities and re-entrant corners increase this vulnerability.This thesis seeks to address the seismic vulnerability of URM structures due to plan irregularities and to contribute to the structural engineering knowledge required to lessen the need for new construction by supporting the reuse, rehabilitation, and ongoing maintenance of existing buildings.A comparative analysis based on the results of nonlinear static and incremental dynamic analyses was carried out on numerical models representing URM structures with plan irregularities typical in Ottawa, Canada.The results from these analyses determined that damages to the structure and the probability of collapse of the structure were reduced overall with the minimization of torsion and full lateral support of the re-entrant corners in the modelled structures.iii

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.
