摘　　要：为了明确工字型钢-混凝土组合梁的竖向抗剪性能,通过建立三维有限元数值模型,对试验过程进行非线性数值模拟与分析,计算结果和试验数据比较吻合。利用该模型,分析工字型钢-混凝土组合梁的竖向受力变形机理,探讨混凝土翼板强度、混凝土翼板的宽度及其有效高度、剪跨比与混凝土翼板的剪跨比对组合梁混凝土翼板抗剪性能的影响,可为工程设计提供参考依据。In order to determine the vertical shear performance of I-section steel-concrete composite beam,a threedimensional finite element numerical analysis model was established to conduct nonlinear numerical simulation and analysis of the testing process.The calculation results agreed well with the test data.By using this model,the deformation mechanism of I-section steel-concrete composite beam under vertical loads was analyzed,and the influences of several parameters such as the strength of concrete flange slab,effective height and width of concrete flange slab,the shear span ratio and shear span ratio of concrete flange on the shear performance of composite beam with concrete flange slab were also discussed,which provided a reference for engineering design.
