Three slab-column specimens, which represent interior, edge, and corner connections, and three isolated column specimens were tested to investigate the axial load transfer in non-slender ultra-high-strength concrete (UHSC, fc′≈200MPa) columns through normal-strength concrete (NSC, fc′≈50MPa) slabs. The test results showed that the confinement of the slab-column joint from the surrounding slab increased...
This paper presents strategies for enhancing the transmission of ultra-high-strength concrete (UHSC) column loads through normal-strength concrete (NSC) slabs in the joint of slab-column connections. Parameters of the investigation were the ratio of column concrete strength to slab concrete strength (fcc′/fcs′), as well as the placement of steel fiber-reinforced concrete, and the installations of...
