| 摘 要： | 对12个脱空钢管混凝土短柱进行了脱空侧偏心受压的极限承载力试验,试验参数为脱空率,研究在一定偏心率下,脱空钢管混凝土短柱力学性能。试验结果表明,脱空率对钢管混凝土偏压构件受力性能与承载力均有影响,随着脱空率的增大,钢管对核心混凝土的套箍作用不断削弱,构件的极限承载力也明显下降,但比脱空的轴心受压钢管混凝土极限承载力折减要少。

| Abstract: | Mechanics behavior tests of 12 specimens of separate concrete-filled steel tubes subjected to eccentric compression on separate side were carried out.Test paramenter is separation ratio.Study on mechanics behavior of separate concrete-filled steel tubes subjected to eccentric compression with a eccentricity ratio.The test results indicate that separation ratio affected both of the mechanics behavior and the carrying capacity of CFST columns under eccentric load.With the load eccentricity ratio increased, th... |
