Abstract
To study the shear bearing performance and failure mechanism of stud shear connectors after strong-corrosion, six groups of stud shear connectors were designed and then welded to the specimen. They are corroded by hydrochloric acid time for 0 h, 2 h, 12 h, 24 h, 48 h, and 72 h. Herein, the loading process, load-slip curve, shear bearing capacity, and failure mode were obtained by the push-out test. The bearing capacity formula was also proposed by the stress mechanism of 84 finite element models. The results of the study on stud shear connectors show that the shear capacity, deformation capacity and slip decrease gradually with the extension of corrosion time. Among them, the enlargement in the diameter exerts considerable influence on their shear capacity. Notwithstanding, the shear bearing capacity slightly increases with stud shear connectors lengthened. The concrete strength grade can strengthen the shear capacity. Finally, the shear bearing capacity formula, taking the reliability coefficient into account, is proposed by the exit test data of 104 stud shear connectors.
