摘　　要：研究了加劲参数对HF1,HF2截面腹板开孔受弯钢构件的影响。采用有限元方法对其进行模拟分析,通过分析得知加劲参数会影响构件的抗弯承载力,可能改变构件的屈曲模式。结果表明,对加劲参数合理取值可以提高构件的抗弯性能。The effects of stiffening parameters on HF1 and HF2 cross section web members with web openings are studied. The finite element method is used to simulate it. Through the analysis, it is found that the stiffening parameters will affect the flexural capacity of the members, and may change the buckling mode of the members. The results show that the reasonable value of stiffening parameters can improve the bending performanee of members.
