摘要
通过拉拔试验,探讨了冷轧带肋钢筋(1200MPa)破坏机理τ-s曲线模式,确定了冷轧带肋钢筋(1200MPa)粘结强度与砼强度、保护层厚度、锚固长度等主要因素的关系,并由试验结果推导出了临界锚固长度,为该级别冷轧带肋钢筋的工程应用提供了可靠的依据。
The conditions of anchorage intensely affect bond-anchorage properties of Cold-Rolled Ribbed Wires and bars in concrete. The effects of concrete strength, thickness of concrete cover, anchorage length for bond-anchorage properties have been investigated on the basis of a lot of pull-out test. By way of experimental statistical regression, the critical anchorage length of the wires and bars has been proposed.
