Finite Element Modeling of Partially Composite Light-Gage Steel Tube Beam with Lightweight Concrete Deck Slab
Bibliographic record
Abstract
For the time being, the steel-concrete composite floors are commonly used in residential, office, and commercial buildings. A traditional composite floor is often constructed with hot-rolled steel. The utilization of hot-rolled steel sections in small and medium-sized buildings is not cost-efficient. Because of the material, cutting process, and labor costs. In addition, the common usage of light-gage cold-formed members, which are often utilized in a non-composite manner, has led to the employment of bigger section sizes. Consequently, the replacement of hot-rolled steel sections with light-gage steel ones to act compositely is a cost-efficient solution. Therefore, this study uses FE modeling with ABAQUS software to investigate the structural behavior of the partially composite light-gage tube beam with a lightweight concrete deck slab. Results of the analysis show that changing the concrete type has a minor influence on strength and stiffness. Changing the concrete type from lightweight to normal weight increases the strength by 3.5%, and increasing the yield stress has a major contribution to the strength. Increasing the yield stress of the beam from 355 MPa to 700 MPa increases the strength by 35.8%.

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.
