Theoretical and numerical approach to calculate the shear stiffness of corrugated metal deck

Abstract: Permanent Metal Deck Forms (PMDFs) currently are used in building application as a lateral beam bracing. In the bridge applications, PMDFs are frequently used to support the wet concrete of bridge decks during the construction phase, but they are not relied on as lateral bracing. The girders in the bridge system are subjected to lateral torsional buckling that occurs under the casting of the bridge deck. In order to improve the stabilizing potential of the PMDF system in the bridge system, it is important to estimate the shear rigidity of metal decks that are used as shear diaphragm.
