| Abstract: | In this paper, through using the elastic plastic theory, the author have theoretically analyzed the stressing state, rule of yielding, calculation of stress and strain and mechanical property of the compressed through axis short column of steel fiber concrete packed by steel tube. On the condition of considering the boundary condition of yielding through unidirectional longitudinal pressure and unidirectional hoop tension, the author bringed forward the bearing capacity calculation formula of the compressed through axis short column of steel fiber concrete packed by steel tube while it is longitudinal pressed and hoop drawn. |
