Steel reinforced concrete (SRC) special-shaped column structures have all properties of steel reinforced structures and special-shaped column structures. The design of SRC special-shaped column joints is of great importance to ensure that this structure can be widely used in earthquake-prone areas. This research adopts a new joint design style, and a pseudo-static test is carried out on three joints (JD-1, JD-2, and JD-3) between the SRC special-shaped column and the RC beam, and one joint (JD-4) between the RC special-shaped column and concrete beam. The working mechanism of joints and the function of steel in the shear resistance mechanism are analyzed. Based on the results of experimental research, this article presents formulas on the cracking capacity and shear resistance capacity of these joints with theoretical and applicative purposes. Taking into account all these facts, the high resistance capacity and reliability of the joint design method are manifested. Some conclusions derived from this research can be used as a reference for engineering practice.

钢筋混凝土（SRC）异形柱结构具有钢筋结构和异形柱结构的所有特性。SRC异形柱节点的设计对于确保该结构可在地震多发地区得到广泛应用至关重要。本研究采用新型接头设计风格，对SRC异形柱与RC梁之间的三个接头（JD-1，JD-2和JD-3）进行了拟静力试验，其中一个接头（JD-4）在RC异形柱和混凝土梁之间。分析了接头的工作机理和钢在抗剪机理中的作用。基于实验研究的结果，本文提出了这些接头的抗裂能力和抗剪能力的公式，具有理论和应用目的。考虑到所有这些事实，表明了联合设计方法的高电阻容量和可靠性。这项研究得出的一些结论可以作为工程实践的参考。
