Abstract

This dissertation presents an inelastic analysis of the behaviour of composite beams with ribbed metal deck.

A layered finite element model is used to allow for any variation in material properties through the thickness. An incremental and iterative technique is adopted using the tangent modulus stiffness approach.

The dependability of the model is checked by means of comparison with some experimental results, obtained from testing composite beams with solid and ribbed slabs.

A study of the effect of the type of loading and the transverse moment in the slab on the deformation and the ultimate capacity of composite beams with ribbed metal deck, is presented.

The effective width of composite beams with ribbed metal deck, subjected to uniformly distributed load, is investigated. The effective width in the inelastic stage and at the ultimate load are also studied.

Finally, a study of the longitudinal cracking of composite beams with ribbed metal deck, is presented. Some design recommendations are presented to account for the longitudinal cracking of composite beams with ribbed metal deck, subjected to a uniformly distributed load over the entire slab.
