Abstract： Through the staticand fatigue test for the bolted-bonded composite steel structure joint, the anti-slip performance, the anti-slip coefficient, the static and fatigue performance of the bolted-bonded composite joint were examined, the results were analyzed in comparison with the test results of friction type high strength bolt. The results show that: ①The static load bearing capacity and anti-slip capacity of boltedbonded joint improved by more than 80% compared with the friction type joint. ②The thicker adhesive layer can improve the anti-slip performance of the bolted-bonded composite specimen. ③After 2 million cycles of cyclic fatigue loading, the anti-slip coefficient of the specimen has basically not changed. ④Micro-analysis found that the failure of the bolted-bonded composite joint mainly consists of two forms: colloidal failure and adhesive interface failure. Compared with friction type joint, the bolted-bonded joint significantly reduces the requirement for the flatness of the friction surface/bonding surface, improves the site work quality, efficiency and shear strength of the connection, and has greater engineering value.
