Experimental studying the effect of transverse reinforcement passing through perfobond holes on the structural behavior of perfobond shear connection

Tóm tắt

The push-out test program was carried out on three groups of nine small specimens to investigate the effect of the transverse reinforcement passing through the perfobond holes on the structural behavior of perfobond shear connector. The number of transverse reinforcements passing through the perfobond holes was changed in each group. One of the groups had no transverse reinforcement, and the other groups had one and two transverse reinforcements passing through the perfobond holes. The quantities observed in this program were the load capacity, the relative slip between the hot-rolled steel and the concrete slab, and the failure mode of specimens. The results showed that the transverse reinforcement passing through the perfobond holes enhanced the load capacity and significantly reduced the relative slip between the hot-rolled steel and the concrete slab.
