摘　　要：采用ABAQUS对一高强钢-混凝土新型组合扁梁的受力性能与传统组合扁梁进行对比,分析钢材强度对新型组合扁梁受力性能的影响。结果表明:与传统组合扁梁相比,新型组合扁梁受力性能更为优越,在截面高度和用钢量相同的条件下,新型组合扁梁承载力提高约9.7%,刚度提高约0.88%;钢材强度对新型组合扁梁承载力影响较大,对刚度影响较小。This paper presents a new type high-strength steel-concrete composite flat beam, its mechanical behavior is compared with the traditional composite fiat beam, and the impact of steel strength on the new type composite flat beam is analyzed by using the large finite element software ABAQUS. The analysis shows that as compared with the traditional composite flat beams, the mechanical behavior of the new type composite flat beam is more superior. Under the same condition of sectional height and steel consumption, the load bearing capacity of new type composite fiat beam is increased by 9.7 percent, the stiffness increased by 0. 88 percent. The strength of steel has greater influence on the load bearing capacity than the stiffness of new type composite flat beam.
