摘　　要：随着我国社会经济的持续高速发展,型钢混凝土组合结构在结构工程领域应用日趋广泛。型钢混凝土结构的内部型钢与外包钢筋混凝土形成整体,共同受力,其受力性能优于这两种结构的简单叠加。型钢混凝土结构中的型钢混凝土柱与钢筋混凝土梁节点构造复杂,受力复杂。节点的承载力往往影响到整个框架的稳定性,研究不同轴压比下的型钢混凝土柱与钢筋混凝土梁节点抗弯性能变得尤为重要。本研究通过在ABAQUS中建立节点模型,对节点在不同轴压比下的抗弯性能进行比对分析,同时对不同梁端约束条件下的节点抗弯性能进行了比对分析。With the continuous and rapid development of China’s social economy,section steel concrete composite structure is widely used in the field of structural engineering.The internal section steel and external reinforced concrete of steel reinforced concrete structure form a whole and joint stress,and its stress performance is better than the simple superposition of the two structures.Section steel reinforced concrete column and reinforced concrete beam joints in steel reinforced concrete structure are complex in structure and stress.The bearing capacity of the joints often affects the stability of the whole frame,so it is particularly important to study the flexural behavior of the joints of SRC columns and RC beams under different axial compression ratios.In the study,through the establishment of joint model in ABAQUS,the bending performance of joints under different axial compression ratio is compared and analyzed,and the bending performance of joints under different constraint conditions is compared and analyzed.
