Abstract
This paper is a theoretical study on beam-to-column connections in thick wall tubular columns. We simplify beam-to-column connections to unti-symmetrical cantilevers and discuss bending of a steel tubular cantilever by a force applied at the virtual free end of it. In the analysis of this probelm, we apply Saint-Venant's flexure theory. We assume that normal stresses over a cross section are distributed in the same manner as in the case of pure bending, and assume that there are two shearing stress components and other three stress components are zero. With these assumptions, we can find the functions of shearing stress components which satisfy the equations of equilibrium, the boundary condition and the compatibility equations.
