摘　　要：随着滚压直螺纹钢筋接头在各种建筑结构中的广泛应用,对钢筋接头的连接质量要求越来越高,因此必须了解钢筋接头的力学性能和强度指标,特别是动荷载作用下的疲劳强度和寿命、接头断裂破坏特征等,以保证整体建筑结构的强度和安全可靠性。通过对多种规格型号大量的滚轧直螺纹钢筋接头进行了动态力学性能试验,找出钢筋接头疲劳断裂的原因和规律,给出有价值的建议和结论。With the rolled straight thread rebar joints widely used in a variety of building structures,the quality of the rebar joints connection becomes increasingly demanding,therefore,it is necessary to understand the mechanical properties and strength indicators of rebar joints,especially the fatigue strength and life,joints fracture characteristics etc under the action of dynamic load,to ensure the strength,security and reliability of the overall building structure.In this paper,the causes and rules of fatigue fracture of rebar joints are found out and some valuable suggestions and conclusions are given by the dynamic mechanical performance tests for large various standard models of rolled straight thread rebar joints.
