Flexural Behavior of Steel–concrete–steel Sandwich Slabs

Aims: Study the flexural behavior of steel–concrete–steel sandwich slabs.

Methodology: Ten SCS slabs full scale specimens were prepared and experimentally tested taking into account the variables of this study.

Study Design: Parametric study is carried out by varying the thickness of (bottom & top) steel plates and types of shear connectors.

Results: The experimental results included ultimate load, vertical deflection at three points, slip between steel plate & concrete core and mode of failure.

Conclusion: Test results show that steel-concrete-steel slabs have good flexural characteristics. The failure modes observed during experiments were occurred due to shear studs rupture, concrete cracking and yielding of steel plates. The shear studs was found to be effective not only in ultimate load capacity but also in vertical deflection.
