[摘要]  以目前实际工程中应用较多的钢筋混凝土坡屋面作为研究对象，将组成这种屋面的基本单元分类，分别对基本单元和工程实例进行对比计算。指出坡屋面的屋脊线能起到类似梁分割楼板的作用，屋脊线相互支撑，整个楼盖共同工作作用明显：分析了坡度变化对坡屋面内力的影响。在不影响建筑功能的前提下，针对坡屋面斜向推力的 水平分量会对柱顶产生较大弯矩的问题，提出解决办法。总结了坡屋面受力特点和实际工程设计中应注意的问题。

Abstract: The RC pitched roof which is often applied in practice is analyzed. The bended line of slab can operate as beam, and fastigium can support one another. The cooperation is obvious in whole floor. Meanwhile, the effect on the internal force in pitched roof differs from gradient. On condition that the building's function is not effected, the solution on that the horizontal projection of thrust in RC pitched roof can cause biggish bending moment in top of column is brought out. The characteristic of the mechanics in pitched roof and the problem should be paid attention to in practice are summarized.
Keywords:  RC; pitched roof; finite element analysis; fastigium
