在过去的3年里，莫纳什大学对混凝土塞向钢管桩的荷载传递进行了研究。在本文中提出的工作报告的结果相结合的拔出，推出，和循环荷载试验进行了15钢管标本部分填充钢筋混凝土与可变长度的嵌入。通过嵌入混凝土塞中的钢筋施加拔出力，通过混凝土塞顶部的厚顶部圆板施加推出力。试验结果包括循环荷载、极限拔出力和极限推出力、混凝土塞的滑移以及部分试件沿桩身沿着的纵向和环向应变。测试清楚地表明，平均粘结强度大大超过预期，并高于以前的调查结果，使用插头没有加强。测试结果还表明，…
Investigation of the load transfer of concrete plugs to tubular steel piles subjected to tension and compression and cyclic loading has been conducted at Monash University over the past 3 years. The work presented in this paper reports on the results of the combination of pull-out, push-out, and cyclic loading tests carried out on 15 steel tube specimens filled partially with reinforced concrete with variable lengths of embedment. The pull-out force was applied through steel reinforcing bars embedded in the concrete plug, and push-out forces were applied through a thick top circular plate on the top of the concrete plug. Test results included the cyclic loading, ultimate pull-out and push-out forces, slip of concrete plugs, and longitudinal and hoop strains along the piles for some specimens. The tests clearly showed that average bond strength significantly exceeds expectations and is higher than the results of previous investigations using plugs without reinforcement. The test results also indicated that...
