Abstract
The majority of steel-concrete sandwich members are monolithic with shear connectors or other anti-displacement stops. However, considering there are only few cases of research available about steel-concrete sandwich members which have no slippage stops, but feature shear reinforcing steel plates in the direction perpendicular to the member's axis, and that furthermore, there is not a study case on the member which is composed of steel elements connected with bitten joints, we conducted a bending test on an actual size structure of this type to confirm its bending behavior. Through our test, we clarifies a typical deformation behavior due to the slippage working between the steel plate and concrete, producing fractural cracks that, without being dispersed are concentrated around the shear reinforcing steel plate. We attempted to establish a model of this relationship in terms of equilibrium of forces between the depth of a crack produced around the shear reinforcing steel plate and the rotational angle. The model was verified to be effective in quantitatively evaluating the bending deformation.
