［摘要］加腋大板作为一种经济合理的结构形式，正在逐步推广，但相关设计方法并不完善。采用ABAQUS程序进行三维实体有限元分析，得出了跨度、加腋宽度、荷载、板厚等因素影响下构件的弯矩分布规律。结果表明，加腋大板在竖向荷载作用下产生了较大的轴力，使得弯矩显著降低，宜采用更合理的办法来估算构件的弯矩进行设计。结合有限元计算结果，拟合得到了加腋大板跨中和支座弯矩的计算公式，具有较高的计算精度。

Abstract:Large haunched slab is a kind of economic and reasonable structural form to be gradually promoted, but related design method is not perfect. Three-dimensional solid finite element analysis using ABAQUS program was carried out to obtain the bending moment distribution laws of the component influenced by factors of span, haunched width, load and thickness. Results show that the large haunched slab produces large axial force under the vertical load, which reduces bending moment significantly, so a more reasonable way should be adopted to estimate the bending moment of the component. Combined with the finite element calculation results, calculation formulas of bending moments at middle-span and bearing were fitted with high calculation accuracy.

Keywords:large haunched slab; finite element analysis; fitting formula
