Finite Element Instability Analysis of the Steel Joist of Continuous Composite Beams with Flexible Shear Connectors
Composite steel/concrete beams may buckle in hogging bending regions. As the top flange of I-beam in that arrangement is restricted from any translational deformation and twist, the web will distort during buckling presenting a phenomenon often described as restricted distortional buckling. There are limited studies available in the literature of restricted distortional buckling of composite st...
متن کاملAnalysis of the Shear Behavior of Stubby Y-Type Perfobond Rib Shear Connectors for a Composite Frame Structure
Shear connectors are used in steel beam-concrete slabs of composite frame and bridge structures to transfer shear force according to design loads. The existing Y-type perfobond rib shear connectors are designed for girder slabs of composite bridges. Therefore, the rib and transverse rebars of the conventional Y-type perfobond rib shear connectors are extremely large for the composite frames of ...
متن کاملInvestigation of channel shear connectors for composite concrete and steel T-beam
This paper evaluates the behavior of channel shear connectors, embedded in a concrete slab, with different concrete materials. The results of a series of limited push-out specimens were presented and discussed. The push-out tests comprise of channel shear connectors in different types of concrete. Reinforcement was included in some specimens, as well. The results showed that using reinforcement...
متن کاملInfluence of Shear Connection Distributions on the Behaviour of Continuous Steel-concrete Composite Beams
For this purpose a finite element model specifically developed for the nonlinear analysis of steel-concrete composite beams is adopted. This finite element model includes material nonlinearity of slab concrete, reinforcement steel, beam steel as well as slabbeam nonlinear partial interaction due to the deformable shear connection. The inclusion of the partial interaction in the composite beam m...
متن کاملFinite Element Response Sensitivity Analysis of Steel-Concrete Composite Beams with Deformable Shear Connection
The behavior of steel-concrete composite beams is strongly influenced by the type of shear connection between the steel beam and the concrete slab. For accurate analytical predictions, the structural model must account for the interlayer slip between these two components. In numerous engineering applications e.g., in the fields of structural optimization, structural reliability analysis, and fi...
