摘要
分析了传统拔出试验的不足之处,提出了一种新型的钢骨与混凝土粘结滑移测试试验方法,实践证明这种试验方法避免了混凝土的受压破坏,实现了钢骨与混凝土粘结面的粘结破坏,从而更加准确地测量了钢骨混凝土粘结-滑移关系。通过试验,分析了混凝土强度、配箍率、粘结强度对粘结-滑移性能的影响。
This article analyzed some shortages of traditional pull-out testing for bond-slip study and proposed a new experimental scheme to test bond characteristics of reinforced concrete. Following this scheme, concrete compression damage can be avoided and damages of bond between steel and concrete can be achived. In addi-tion, this paper also explored the relationships between bond characteristics and some sensitive parameters, in-cluding concrete strength, hoop reinforcement, and bond length. Preliminary research results of bond behav-iors uder repeated loads were presented.
