钢管混凝土结构由钢管和混凝土共同组合而成，常被用于高层、超高层以及相关抗震实践领域。由于这种结构优越的性能，钢管混凝土柱-钢梁也随之得到了广泛使用，与此同时，很多学者已经对钢管混凝土柱与梁节点展开了一系列深入的研究工作，然而对于穿筋连接节点构造做法却仍然处在初步探索阶段，其受力性能仍需进一步分析。 本文利用ABAQUS软件建立钢管混凝土柱-钢梁穿筋节点模型，并与已有试验数据进行校对，验证有限元方法准确性；通过考虑所配置钢筋的截面面积（钢筋直径）与数量、钢管壁的厚度、轴压比和混凝土强度等参数，设计20个有限元模型试件，并对各个试件在循环荷载下的抗震性能指标（滞回曲线、骨架曲线、刚度和强度退化曲线）及各个试件的应力等进行了深入研究。 研究结果表明：在循环荷载作用下，基本构件的滞回曲线饱满，呈纺锤形，无明显的刚度退化和捏缩现象，表现出良好的抗震性能；穿筋类构件节点部位的钢筋截面面积，即钢筋直径取16mm~20mm时，抗震性能能够有效发挥；节点部位必须设置钢筋，且钢筋宜布置在牛腿上下翼缘两侧，钢筋数量至少为8根，此时节点抗震性能才能有效发挥；钢管混凝土柱的柱端轴压力对构件节点部位承载力和抗震性能影响很小；随着钢管壁厚度的增加，梁柱连接处刚度变大，节点承载力提高，但是结构的延性大幅降低，这不利于结构抗震；当混凝土强度达到一定数值时构件直接破坏，因此在实际工程中应合理配置。 本文深入分析了钢管混凝土柱-钢梁穿筋节点试件在循环荷载作用下的抗震性能，得出的结论对钢管混凝土柱-钢梁穿筋节点的理论研究和工程应用具有一定的参考价值，为进一步研究打下了良好的基础。

The concrete filled steel tube structure possesses advantages over either pure steel or concrete columns, and it is often used in high-rise and related seismic engineering practice. The superior performance of this structure，the concrete-filled steel tubular has been widely used.Now the performance of concrete filled steel tubular column and steel beam joints has been studied in depth , but the exploration and research of concrete filled tube column to beam with penetration bars is rare,its mechanical properties are need further analysis. Through comparison with experiments,we make use of ABAQUS to verify the accuracy of the finite element method and conduct the finite element analysis with full-scale simulation. We establish twenty F.E.models , for considering the behavior influence of cross-sectional area of reinforced（bar diameter）,thickness of enforced loop plane, axial compression ratio and thickness of steel tubular.We analyse the hysteretic performance of structure, stress of steel and the node of penetration bars by finite element calculation results. The analytical result is: the hysteretic curve of Enforced inner Loop Joint is full and spindle in cyclic loading.Structure have not obviously stiffness degradation and Knead shrinkage phenomenon, structure have good seismic performance;The node parts of penetration bars should choose the appropriate reinforcement area,when the steel bar diameter 16 mm to 20 mm,seismic performance can be effectively;The node parts of penetration bars must be set reinforcement and reinforced appropriate decorates the brackets on both sides of the upper and lower flange.In total ,at least eight root, and it have good seismic performance;column end pressure of nodes bearing force and seismic performance of very small; with the increase of steel pipe wall thickness, variable on the stiffness of beam column joints, the bearing capacity of nodes increases, but the ductility of the structure to reduce, which is not conducive to anti-seismic structure;when the concrete strength reaches a certain value component failure,so it should reasonable configuration in actual engineering . This paper deeply analyzes the seismic performance of the connection joint between the concrete filled tube column to beam with penetration bars cyclic loading, the conclusion of the node for the theoretical research and engineering application has a certain reference value, laid a good foundation for further study.
