Ductility of Composite Beams with Trapezoidal Composite Slabs
Deep trapezoidal slabs supported compositely on steel I-beams by headed mechanical stud shear connectors provide a popular and economical structural solution for flooring in steel building frames, and they are used widely. When the ribs in the sheeting are oriented orthogonal to the steel beams so that longitudinal stresses traverse the voids, predicting their structural response is difficult, and full-scale testing is very costly. Because of this, an inexpensive and accurate means of analysis that incorporates the non-linear response of the shear connection is much needed. This paper presents such a finite element technique, which incorporates non-linearity in the concrete, steel joist, reinforcement and the shear connection; the latter being derived from specialised push test data embodying the complex interactions in the trough region of the slab. The procedure is used to analyse two full-scale beams for which relevant push test data is available, and the agreement is shown to be very good.
