文摘

The structural behavior of PBL using UHPC is studied by push-out tests. The impact of steel fibers content in UHPC on the behavior of PBL is studied. The shear-resistant capacity of the PBL embedded in UHPC grout is analyzed. Equations to predict the shear capacity of PBL in steel-concrete joint are proposed.
