| 摘 要： | 为研究钢管壁开洞钢管混凝土组合柱的受剪承载力及加强措施的效果,对1个管壁不开洞和3个管壁开洞的组合柱试件进行受剪试验。结果表明:试件为剪切破坏;管壁开洞降低了试件的受剪承载力;加强措施提高了管壁开洞试件的受剪承载力。最后,提出了管壁开洞但采取加强措施组合柱的受剪承载力计算公式,试件受剪承载力计算值与试验值吻合较好。

| Abstract: | To study the shear strength of composite column whose steel tube has large openings and to study the effects of strengthening measures,4 concrete-filled steel tube composite column specimens were tested,in which one specimen had no opening on its steel tube wall and 3 specimens had large openings on their steel tube wall. The test results showed that all the specimens failed in shear; openings on the steel tube wall decreased the shear strength of the specimens. The strengthening measures increased the shear strength of specimens whose steel tube had large openings. The formulas to calculate the shear strength of concrete-filled steel tube composite columns whose steel tube had large openings were proposed,the calculated shear strength of the specimens had good agreement with the test results. |
