An analysis of the bending shear stress of the centrifugal concrete filled thin-wall steel tube

As shown in the projects, under lateral outer forces, the bearing carrying capacity of the centrifugal concrete filled thin-wall steel tube is closely related to its internal bending shear stress as well as the normal stress distribution of section. So far, no research is done on this. This paper proposes formulas for the calculation of the bending shear stress of its outer steel tube and inner concrete, therefore provides the theoretical support for the further study on the simplified calculation method of the shear resistance.
