Abstract: Recycled tire rubber-filled concrete (RRFC) is employed into the steel-concrete
composite structures due to its good ductility and crack resistance. Push-out tests were
conducted to investigate the static behavior of different studs in normal concrete and RRFC.
The results of the experimental investigations show that large studs lead a higher ultimate
strength but worse ductility in normal concrete. Rubber particles in RRFC were shown to
have little effect on shear strength when the compressive strength was equal to that of
normal concrete, but can have a better ductility for studs in rubber-filled concrete. Besides
that the quantity and width of cracks can be reduced by RRFC efficiently. Based on the test
result, a modified empirical equation of ultimate slip was proposed to take not only the
compressive strength, but also the ductility of the concrete into consideration.
