中文摘要：
该文以实际工程为背景,对超高层建筑中常采用的钢管混凝土柱与伸臂桁架连接节点进行了大比例模型滞回加载试验。试验结果表明试件具有较高的极限承载力,耗能能力较好,试件的破坏模式最终表现为桁架近加载梁的上弦杆变截面处翼缘受拉断裂以及荷载反向后的弦杆压曲变形,建议将变截面焊接连接位置向弦杆中部偏移并严格控制其焊缝质量。
英文摘要：
Based on a practical engineering project, the large scale cyclic test on the connection between a concrete filled steel tube column and a outrigger truss is conducted. Test results indicate that specimens show relatively satisfying load carrying capacity as well as considerable ductility, and that the failure mode exhibit as the flange fracture of the upper chord and buckling under compression. It is suggested that the welding connection section should be moved to the middle of the upper chord and the welding quality should be control strictly.
