摘　　要：针对工字型钢-混凝土组合梁的受弯性能,建立了三维有限元数值分析模型,对试验全过程进行了非线性数值模拟,计算结果与试验数据吻合较好。利用该模型,分析了工字型钢-混凝土组合梁的受力变形机理,探讨了钢梁强度等级、混凝土强度等级、钢梁腹板厚度、混凝土板厚度及纵横向配筋率等对组合梁受弯性能的影响,为工程设计提供参考依据。Three-dimensional model of I-shaped steel-concrete composite beams was established in order to research the flexural behavior of composite beams. The whole experiment process was simulated nonlinearly. Comparisons between the experiment analysis and calculated results showed good correlation. The force mechanism of I-shaped steel-concrete beams was analyzed. The effects of the main parameters, such as steel strength grade, concrete strength grade, steel webs thickness, concrete plate thickness and reinforcement ratio, on flexural behavior were analyzed by using the presented model. The results derived from analysis provide some useful references for engineering design.
