Abstract: To study the bearing performance of the Tibetan beam-column joint under the damage state of Queti inclination, seven full-scale joint models were fabricated (including one undamaged joint, four damaged joints with different Queti inclination degrees and two reinforced joints) and tested under vertical static load. The failure mode, stress state of members, load-displacement curve characteristics of the inclined joints under vertical load and their variation with inclination degree were analyzed. The bearing stiffness, yield load, ultimate load and ductility factor of the joints were determined, and the improving effect of column foot reinforcement on bearing performance of the inclined joints was investigated. The results show that the local failure phenomena of the joints mainly include crushing of Dianmu bottom perpendicular to grain, cracking of Dianmu flank, and separation of contact surface of Gongmu-end and beam. Dianmu is the weakest part of the joints under vertical load with the most serious damage. Inclination of Queti will accelerate the damage process of the joints, with the failure mode converted from uniform compression failure to eccentric compression failure and conceivable instability failure eventually. Compressive strain of Queti is higher in the middle and lower at the both sides along the longitudinal direction, with the non-uniformity increased by the increase of inclination degree. Under inclined state, the compressive strain at front side of Gongmu is higher than that at back side, while the back strain of Dianmu is higher than the front strain. The bearing stiffness, yield load, ultimate load and ductility factor of the joints decrease with the increase of inclination angle, the decreasing rate of the bearing stiffness under uniform load is the fastest, and the stiffness of the joint with 12° inclination angle is 66% less than that of the undamaged joint. The bearing performance of the joints is improved after reinforcing the column foot, and the improving in ductility factor is the most significant, with 70% improvement for the joint with 12° inclination angle.
