摘　　要：在复合曲梁正应力公式的基础上，进一步导出了其剪应力和径向应力的计算公式，从而使复合曲梁的应力问题全部得到解决．作为特例，也可以从上述公式得到该梁在具有纵向对称面，且载荷作用在该平面内时的相应公式．最后给出了计算实例．Based on the nornal stress formula for the composite curved beam, the formulae of the shearing and radial stresses for the composite curved beams are further derived. To verify the theory, these stress formulae are simplified to those for the. beams with longitudinal symmetrical plane and loaded in the plane. In the paper a numerical example is given at the end.
