摘　　要：针对卷边工形变截面构件在压弯作用下的面内稳定承载性能进行研究,并在已有的卷边工形等截面压弯构件面内稳定承载力公式的基础上,参照CECS 102∶2002《门式刚架轻型房屋钢结构技术规程》中的变截面构件设计方法,给出卷边工形变截面构件压弯平面内稳定承载力的计算公式。楔率是影响变截面构件稳定承载力的重要因素,设计了一系列算例,重点考察楔率对变截面卷边工形构件稳定承载性能的影响,同时也验证了所给出的平面内稳定承载力计算公式的准确性和适用性。The in-plane stability bearing capacity of lipped H-sectlon tapered members under beth compression and bending is studied, and corresponding calculation formula is also given based on the existing formula of current Chinese related technical codes. For tapered members, stability bearing capacity is seriously affected by tapering ratio, thereby a series of examples are designed to evaluate the influence of tapering ratio on stability bearing capacity of lipped H-section tapered members, meanwhile the accuracy and validity of the calculation formula proposed in the study is also confirmed.
