Abstract
The bond strength of welded wire fabric (WWF) in concrete bridge decks was investigated by testing 22 pullout specimens for bond strength up to their ultimate capacity. The pullout study showed that after the bond between longitudinal wires and concrete failed, the specimens resisted additional loads due to the anchorage effects of transverse wires and shear strength of welds. This increase in bond strength ranged from 16 to 771%, depending upon the type and arrangement of longitudinal and transverse wires. The transverse wires and shear strength of the weld, therefore, make large contributions to the bond strength of the welded wire fabric in concrete bridge decks.
