| 摘 要： | 针对《门式刚架轻型房屋钢结构技术规程》中刚架柱计算长度系数取值上存在的一些问题－－适用范围小（规定限于屋面坡度很小时公式适用），而且未考虑斜梁内轴力的不利影响；本文利用有限元法编程对柱脚铰接有侧移楔形变截面单跨门式刚架的整体稳定性进行了大量算例分析，提出了实用的确定楔形刚架柱的计算长度系数的方法。 |
| 关 键 词： | 楔形构件 门式刚架 计算长度系数 稳定性 钢结构 |

| Abstract: | The technical specification for structure of one story light weight building with poral frames (CECS102:98) is just promulgated in China, however, in the party of effective length coefficients of the frames column, some problems still remained. This paper used the finite element method to do a lot of numerical studies in single span portal frames with tapered members for hinge support. The influence of the axial forces acting on beams is invovled in the study. Practical methods are given on effective length coefficients of the frames column. |
| Keywords: | tapered member portal frame effective length coefficient stability steel structure |
