- Abstract
A embedded connector with flange plate was proposed. According to the actual project, eight specimens were fabricated and tested and their relationships of load-slip curve in different stages were analyzed. The influence factors of the shear bearing capacity and failure modes of the connector were studied. The results showed that when the width-to-thickness ratio of the steel flange plate satisfied certain conditions, the shape of the crack in the thickness direction of the slab was a straight line and the shape of the crack in width of the concrete slab was corrugated. Otherwise, the buckling of the flange plate was occurred and concrete cracks were not fully developed. The loading could not be implemented due to the buckling of flange plate and the tests were finished prematurely. The shear capacity of the specimens that the flange didn't buckle in advance was about 1. 5 times of the theoretical value of the current theory on embedded connector, which proved that the flange plate significantly improved the shear capacity of the innovative connector.
