摘　　要：为考察多个因素对两跨连续钢-混凝土组合板静力性能的影响,通过ABAQUS软件建立组合板静力性能的有限元模型,用7组足尺试验数据验证该模型的可靠性。结果表明:有限元模型可有效预测钢-混凝土组合板的静力性能,试件极限承载力的模拟值与试验结果最大相差80%;在弯矩预测方面,有限元模拟值与试验结果最大相差40%。In order to investigate the influence of multiple factors on the static performance of two-span continuous steel-concrete composite slabs,a finite element model of the static performance of composite slabs was established by using ABAQUS software.The reliability of the model was veri-fied by seven sets of full-scale test data.The results show that the finite element model can effec-tively predict the static performance of steel-concrete composite slabs,and the maximum difference between the predicted value of the ultimate bearing capacity of the specimens and the experimental results is 80%.At the same time,in the prediction of bending moment,the maximum difference between the finite element prediction value and the test result is 40%.
