Non-Linear Pushover Analysis of Tall Buildings with Post-Tensioned Slabs and Rigid Core Designed Under Peruvian Codes
Bibliographic record
Abstract
Currently at Peru tall building over 30stories began to be built.However, Peru structural design codes are based on medium and low-rise buildings.As well, posttension slab is used to these high rise buildings.The objective of this research was to evaluate the behavior of 6 high-rise buildings through nonlinear Pushover analysis.These buildings include rectangular and square floor plans of 40, 36 and 32 floors, and were designed considering the Peruvian regulations E 0.20 'Loads', E 0.30 'Earthquake Resistant Design' and E 0.60 'Reinforced Concrete'.Rigid core systems were used, varying the compressive strength of the concrete.Also 35 cm thick post-tensioned slabs were used as part lateral structural resistant system, which behavior presented high punching shear forces due earthquake loads.The results of the nonlinear pushover analysis show that the capacity curves are fragile because the hinges of the walls fail in shear instead of in bending moment-compression.On the other hand, it was also found that buildings with 32 and 26 levels with a rectangular floor plan are unable to meet the displacement demand.

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.
