ABSTRACT

In order to address the abovementioned problem related to shear deformation of the beam material layers, a Higher-order Beam Theory (HBT) has recently been applied by Sheikh and coworkers (Chakrabarti et al. 2012) for an accurate modelling of steel concrete composite beams having partial shear interactions. The cross-sectional warping of the beam material layers produced by the transverse shear stress is modelled by taking a higher order (3rd order) variation of longitudinal displacement of the fibers over the beam depth. However, these studies are confined to linear elastic response of these two layered composite beams.
