摘　　要：采用有限元软件ABAQUS分别建立纯工字型钢-混凝土组合梁、钢梁包混凝土组合梁以及型钢混凝土组合梁模型,指出不同类型组合梁之间抗弯承载力与混凝土模型损伤的差异,讨论混凝土强度与钢材屈服强度等参数对组合梁受弯性能的影响,提出不同强度等级材料搭配时组合梁类型选取类型方法,在此基础上,提出了不同强度等级材料搭配时组合梁类型最佳选取方法.This paper sums up the method of finite element analysis on the bending performance beam, steel beam concrete composite beam and steel reinforced concrete composite beam about their ultimate ben-ding resistance. It also points out the difference on the capacity of withstand bending and the damage of concrete models among different kinds of combination beam. This paper discusses the infuence of concrete strength, yield strength of steel products and puts forward methods of matching materials of different grades. On the basis of these, the prospect of the research on the calculation of the collaborative work degree of materials of the is forwarded.
