双箱钢-混凝土组合梁结构是一种新型钢-混凝土组合结构，具有较好的应用前景。为研究该种组合梁的结构性能，并分析其强度和刚度的主要影响因素，设计了两根组合梁模型进行试验研究。通过测试其跨中截面应变、纵向挠度、承载能力等参量来分析该组合梁的荷载应变曲线、荷载挠度曲线等。借助有限元软件ANSYS 建立了组合梁的三维空间有限元模型，考虑材料非线性，对该组合梁模型进行了有限元分析。分析结果与试验结果的比较分析表明，两者吻合良好，表明该研究对工程应用具有一定的指导作用和参考价值。
雙箱鋼-混凝土組閤樑結構是一種新型鋼-混凝土組閤結構，具有較好的應用前景。為研究該種組閤樑的結構性能，併分析其彊度和剛度的主要影響因素，設計瞭兩根組閤樑模型進行試驗研究。通過測試其跨中截麵應變、縱嚮撓度、承載能力等參量來分析該組閤樑的荷載應變麯線、荷載撓度麯線等。藉助有限元軟件ANSYS 建立瞭組閤樑的三維空間有限元模型，攷慮材料非線性，對該組閤樑模型進行瞭有限元分析。分析結果與試驗結果的比較分析錶明，兩者吻閤良好，錶明該研究對工程應用具有一定的指導作用和參攷價值。

The double - box steel - concrete composite beam structure is a new type of steel - concrete composite structure that has wide application prospect. In order to further investigate the mechanical performance of the composite structure and analyze the influential factors of strength and stiffness,two specimens model beam were designed and studied. Through the measuring pa-rameters such as the strain of mid - span cross - section,longitudinal deflection and bearing capacity,the loading - strain curve and loading - deflection curve were analyzed. By consideration of the material nonlinearity,a 3D model for the composite beam is established and analyzed by ANSYS. Finally,the comparative analysis between experimental test and finite element simulation is conducted,which shows a high correlative agreement with each other. This research has a certain guidance and reference value for engineering application.
