Abstract
The proper application of the capacity design approach in earthquake resistant design requires a deep understanding of the behavioural characteristics of the different members comprising the structure. As well, an accurate assessment of the strengths of these members is essential. Of particular importance are the relative strengths of the beams and columns. The analytical investigation carried out in this paper was primarily focused towards assessing the effects of the floor slab on enhancing both the strength and stiffness of the supporting beams under negative (hogging) moments.For this purpose, a nonlinear finite element analysis of an exterior slab-beam-column subassembly was performed. The computer program is based on a nonlinear iterative secant stiffness formulation. Three different three-dimensional finite elements were used to model the structure. The finite element analysis performed showed significant contribution of the slab reinforcement and yielded valuable results regarding the assessment of slab contribution under negative moments when the structure is subjected to lateral earthquake type loads. The results are compared with the provisions of both the Canadian and American codes. Recommendations are given for an effective slab width for exterior connections under similar conditions.

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 it
