摘　　要：给出了一般截面形状的复合曲梁在复杂载荷作用下正应力的计算公式。作为特殊情况，该梁在平面弯曲时的相应公式也可以从上述公式得到．最后给出了计算实例。The formulas for calculation of normal stress under complicated loads in a compo-site curved beam with general sectional shape are derived. The componding stress formulasmay be obtained accordingly in the special case of plane bending of beams. A numericalexample is given for verification.
