摘　　要：剪力钉的剪切刚度是钢-混凝土结构设计和计算中的一个重要参数,一般通过分析剪力钉模型试验的实测结果得到。剪力钉的剪切刚度是个综合且复杂的量,缺乏统一的取值标准和计算方法。根据剪力钉推出试验的测试结果,综合欧洲规范4条文和学者推荐的计算方法,分析得到了22×200剪力钉在界面无摩擦组合结构中纯剪下的剪切刚度值,并对相关影响因素进行讨论。The shear stiffness of shear studs is an important parameter in steel-concrete structure design and calculation,generally calculated by the measured results of push-out-tests.The shear stiffness of shear studs is an integrated and complex value,lacking of uniform standards and calculation methods.According to the results of push-out-tests,foreign-related specification clauses and scholars recommended methods,this article calculates shear stiffness of22×200shear studs in the interface without friction under pure shear,also discusses the relevant factors.
