［摘要］将对称平直线加腋梁简化为以横截面形心的连线为中性轴的空间曲杆，推导了其解析解。给出了这种加腋梁在均布荷载作用下的计算参考表格，并通过实例和三维有限元的数值解进行了对比，提出了对称平直线加腋梁解析解的修正方法。将对称平直线加腋梁和对称斜直线加腋梁进行了对比和分析，得出了一些有意义的结论。

Abstract:Symmetric parallel-haunched beams are simplified to spacial curved beams whose neutral axes are geometrical centers of the cross-sections, and the mathematic solution and reckoner of the beams under uniform load are given. An example is given to demonstrate the solution by the finite element analysis, and the modified method about the mathematic solution is proposed. The comparison between parallel-haunched beams and diagonal-haunched beams is made, and some practical conclusions are got.
Keywords:parallel-haunched beam; uniform load; mathematic solution; modified method
