Abstract To adapt to the development of prefabricated composite beam, a new stainless steel removable bolt connector was developed, and the mechanical performance degradation law under fatigue load was studied. First of all, Through the literature and market research, fully considering of the advantages and disadvantages of the existing bolts, a new stainless steel removable bolt connector for prefabricated composite beam was designed and produced; Secondly, six sets of push-out tests with new bolt connections were conducted for static and fatigue tests. Comparing the failure mode of specimens after static load and fatigue load with different cycle times, the residual bearing capacity, residual slip amount, shear stiffness and ductility coefficient of the new bolt connections during fatigue load were analyzed; Finally, based on the fatigue accumulation damage theory and the material residual strength model, the damage degree of the new bolt connector during fatigue loading was determined, the calculation model of bolt bearing capacity was established. The results show that the new bolt connector has different deformation and failure characteristics of section under static and fatigue loads; the mechanical properties of the new bolt connector show irreversible degradation after fatigue load. In this test, after 2.7 million fatigue loadings, the residual bearing capacity of specimens deteriorates by 12.1%, ductility coefficient deteriorates by 67.6%, shear rigidity deteriorates by 12.9%, and the degradation is obvious. The calculation result of the proposed residual bearing capacity of bolt connectors shows good agreement with the test value.
