Composite Steel-Concrete Beams With Corrugated Steel Webs

Abstract

Corrugated steel web beams are widely used in structural engineering applications, and are sometimes more preferred than the flat web steel beams especially in the slender web, due to their aesthetic appearance and high strength-to-weight ratio. In many cases, the maximum capacity of such beam is governed by the geometry of the corrugation profile. Merging a composite action with the accordion effect in one beam is considered as a modern technique of construction. This research program investigates new composite steel-concrete beams with corrugated steel web. The research focused on composite beams of zigzag-corrugated web subjected to two-point loading flexure test simply supported. The study includes a numerical model using finite element analysis, the model was verified against experimental results. FEM was carried out to investigate the behaviour of composite steel-concrete beams with corrugated web including local & global behaviours, and to examine a wide range of parameters such as the corrugation angle, corrugated web depth, panel width and thickness, in addition to concrete slab width. Results are presented in terms of load-deflection, load-concrete strain, load-steel strain plots and deformed shapes of girders at ultimate loads. The finite element model also investigates the effect of
