    • Abstract:
      Seven-wire strands are commonly used in pretensioned

      concrete ties, but its bonding mechanism with concrete needs

      further examination to provide a better understanding of some

      concrete tie failure modes. As a key component in the finite

      element (FE) analysis of concrete crossties, macro-scale or

      phenomenological FE bond models are developed for sevenwire

      strands in this paper. The strand-concrete interfaces are

      homogenized with a thin layer of cohesive elements applied

      between the strand and concrete elements. Further, the

      cohesive elements are assigned traction-displacement

      constitutive or bond relations that are defined in terms of

      normal and shear stresses versus interfacial dilation and slip.

      The bond relations are developed within an elasto-plastic

      framework that characterizes the adhesive, frictional and/or

      dilatational bonding mechanisms in the interface. The yield

      functions and plastic flow rules specific for the seven-wire

      strands are presented. The bond parameters are calibrated from

      untensioned pullout tests and pretensioned prism tests

      conducted on concrete specimens. The bond models are then

      verified with (1) the surface strain data measured on actual

      concrete crossties made at a tie manufacturing plant, and (2) the

      force-displacement relation obtained in a center negative

      moment test conducted also on concrete crossties.
