To investigate the seismic behavior of joint between special-shaped concrete-filled steel tubular (CFST) column and H-section steel beam, a pseudo-static test was carried out on five specimens with scale ratio of 1:2. The investigated factors include stiffening types of steel tube (multi-cell and tensile bar) and connection types (exterior diaphragm and vertical rib). The failure modes, hysteresis curves, skeleton curves, stress distribution, and joint shear deformation of specimens were analyzed to investigate the seismic behaviors of joints. The test results showed the connections of exterior diaphragm and vertical rib have good seismic behavior and can be identified as rigid joint in the frames with bracing system according to Eurocode 3. The joint of special-shaped column with tensile bars have better seismic performance by using through vertical rib connection. Furthermore, a finite element model was established and a parametric analysis with the finite element model was conducted to investigate the influences of following parameters on the joint stiffness: width-to-thickness ratio of column steel tube, beam-to-column linear stiffness ratio, vertical rib dimensions, and axial load ratio of column. Lastly, preliminary design suggestions were proposed.

为了研究异形钢管混凝土柱与H型钢梁之间节点的抗震性能，对比例为1：2的五个样本进行了拟静力试验。研究的因素包括钢管的加固类型（多室和拉伸钢筋）和连接类型（外隔板和垂直肋骨）。分析了试件的破坏模式，磁滞曲线，骨架曲线，应力分布和接头剪切变形，以研究接头的抗震性能。测试结果表明，外部隔板和垂直肋骨之间的连接具有良好的抗震性能，并且可以根据欧洲规范3将其识别为带有支撑系统的框架中的刚性接头。异形柱与拉力杆的连接通过采用竖向肋骨连接具有更好的抗震性能。此外，建立了有限元模型，并用有限元模型进行了参数分析，以研究以下参数对接头刚度的影响：柱钢管的宽度与厚度比，梁与柱的线性刚度比，竖向肋尺寸和柱的轴向载荷比。最后，提出了初步的设计建议。和柱的轴向载荷比。最后，提出了初步的设计建议。和柱的轴向载荷比。最后，提出了初步的设计建议。
