摘　　要：组合梁腹板开洞会削弱其承载力,工程上经常对洞口设置加劲肋进行补强设计。本文通过对美国AISC和欧洲SCI/CIRIA中普通腹板开洞组合梁计算方法进行介绍,并参考我国已有的腹板开洞组合梁试验研究及计算方法得出带加劲肋的腹板开洞组合梁计算公式,其适用性需要进一步的试验研究来验证。Engineering stiffeners are set to reinforce the composite beam whose capacity is weaked by the web openging.This paper gets the method of the openings with stiffeners in composite beams through the introduction of the United States AISC and Europe SCI/CIRIA and reference to experimental study of the web openings in composite beams,the applicability need further experiment to verify.

关 键 词：腹板开洞 组合梁 加劲肋 极限承载力
