- Abstract:
-
On the basis of embedded connectors, a kind of embedded connectors with flanges is proposed. According to the actual engineering, push-out tests of 8 specimens are carried out, and the relationship between load-slip curves at different stages is analyzed, and the shear resistance is studied. Influencing factors and failure modes of bearing capacity. The results show that: when the width-thickness ratio of the steel flange plate meets certain conditions, the cracks at the thick part of the concrete slab are straight lines, and the cracks at the width of the slab are corrugated lines; , the concrete cracks were not fully developed, and the loading could not continue due to the instability of the flange plate, so the test ended early. The shear bearing capacity of the unbending specimen of the flange plate is about 1.5 times of the theoretical calculation value of the bearing capacity of the existing embedded connector, which proves that the flange plate significantly improves the resistance of the new connector compared with the embedded connector. shear capacity.
