摘　　要：针对变截面门式刚架柱的稳定性计算中,采用大头截面参数还是小头截面参数进行探讨,并提出稳定系数φ'b的简化公式。通过对稳定系数φ'b的对比分析验证了简化公式的安全性和可靠性。本文建议现行《门式刚架轻型房屋钢结构技术规程》CECS102:2002(以下简称《门刚规程》)在今后修编时采用与现行《钢结构设计规范》GB50017-2003接轨的本文简化计算公式。The issue that using bigger section parameters or smaller section parameters in the stability calcula- tion of tapered column in gabled frames. Simphfied formula for calculation of stability coefficient φ＇b has been raised. Verify the safety and reliability of the through the comparative analysis of stability coefficient φ＇b recommends that the existing technical specification for steel structure of light-weight buildings with gabled frames CECS 102： 2002 should use the simplified formula in the next revision, so that integrate with the Code for design of steel struc- tures GB 50017--2003.

关 键 词：稳定系数 大头截面参数 简化公式
