【Abstract】 Displacement functions suitable to analyze the torque behaviour of core tube with holes in four sides are assumed, and the simple formulas calculating the shear forces and torque angle of core tube are derived. The comparison with the results of SAP84 through numerical example shows that the method of this paper is much simpler and more time-saving.更多还原
