摘　　要：在建研院实验室进行了58个钢管混凝土抗剪试件的试验研究, 试验考虑了剪跨比、轴压力、套箍指标等多种参数的影响, 剪跨比分别为1. 0, 0. 5, 0. 4和0 .14, 轴压比分别为0, 0 .2和0. 4, 并采用了不同的钢管规格和混凝土强度等级, 详细研究了相关参数的影响, 并推荐了钢管混凝土柱的受剪承载力计算公式。The experimental study on the shear resistance performance for 58 concrete filled steel tube specimens was made in the lab of China Academy of Building Research. The influential parameters such as shear span, axial force, confined coefficient, and so on, were taken into consideration. The shear spans of the tests are 1.0, 0.5, 0.4, and 0.14. The axial compression ratios are 0, 0.2 and 0.4. Different size specifications of steel tube and different strength grades of concrete are also included. Based on the test results, the method for calculating the shear bearing capacity of concrete filled steel tube columns is recommended.
