为研究折线形钢梁的受力性能，采用ANSYS有限元分析软件对其受力性能进行了数值模拟，并运用力法推导了折线形钢梁的内力计算公式以及截面应力计算公式，得出了水平推力、跨中位移和跨中弯矩随着坡度的变化规律，对比两者的分析结果表明力法与ANSYS计算结构内力和跨中截面应力较为接近。

To study the mechanical behavior of mansard steel beam,mansard steel beams were simulated by ANSYS software,and then deduce the calculation formula of internal force and section stress by unit-force method. The change regulation of horizontal thrust,mid-span displacement and mid-span moment were obtained,through comparison of two methods,we find that the results of structure internal force and section stress by the unit-force method are similar to the ANSYS.
