本文介绍了对混凝土填充管状圆形空心截面（CHS）连接的一系列试验。测试了四种类型（T、Y、K 和 KT）的 12 个连接。试验涵盖了60和75两种不同的弦壁长细比（D/t）。试件首先采用钢管焊接形成连接，然后在主弦全长内填充自密实混凝土。测量了测试样本中使用的钢材和混凝土的材料特性。每个连接均在分支构件承受轴向拉力的情况下进行了失效测试。弦杆冲剪破坏是试验过程中观察到的主要破坏模式。测试结果还与当前 AISC 设计预测进行了比较，当前 AISC 设计预测仅适用于圆形空心型钢管连接。当前 AISC 标准预测的设计强度对于本研究中的测试样本来说相当保守。因此，设计时应考虑混凝土的贡献，因为它对CHS管混凝土连接的极限承载力有显着影响。
A series of tests on the concrete-filled tubular circular hollow section (CHS) connections is presented in this paper. Four types (T, Y, K, and KT) of 12 connections were tested. The tests covered two different chord wall slenderness ratios (D/t) of 60 and 75. The test specimens were first welded by steel tubes to form connections, and then self-compact concrete was filled in the main chord in full length. The material properties of steel and concrete used in the test specimens were measured. Each connection was tested to failure with the branch member loaded in axial tension. Punching shear failure of chord member was the main failure mode observed during the tests. The test results were also compared with current AISC design predictions, which are only for circular hollow section steel tubular connections. The design strengths predicted by the current AISC standard are shown to be quite conservative for the test specimens in this study. Therefore, the contribution of concrete should be considered in the design because it has a significant effect on the ultimate bearing capacity of concrete-filled CHS tubular connections.
