Abstract

Abstract

In order to strengthen the interfacial bonding effect of long-span steel-concrete composite beams, a cross-shaped perfobond strips (PBL) was proposed based on the actual engineering structure.The push-out tests of 1 set of stud strips and 3 sets of cross-shaped PBLs were conducted.The failure modes and load-displacement curves of strips were studied.The results showed that the shear strength of cross-shaped PBL with similar cross-section areas was much higher than that of stud strips.The cross-section width and concrete strength grade had the greatest influence on the shear performance of cross-shaped PBLs.The shear capacity of cross-shaped PBLs increased with the increase of the thickness of perfobond strips.The shear stiffness increased with the increase of strip height.
