| 摘 要： | 变截面门式刚架因其节省钢材而广泛被应用，但其设计中有两个问题一直没有统一方法：（1）变截面位置的选择；（2）截面突变处梁高的选择及截面各处强度验算。本文通过简单可行的方法进行优化选择，解决了此问题。 |

| Abstract: | Non uniform portal Frame has been widely used with less consumption of steel. However there is no consistent way to solve the two following problems: one is where to locate the section break and the other is how to choose the height of the section break and check the stresses at different localities of the inclined beam. In the paper, an efficient method of solving the problems above is presentes |
| Keywords: | two segment variable cross section three segment variable cross section section break |
