Confinement Effect of Narrow Baseplates or Reaction Area on Anchor Breakout, Part 2

The primary objectives of this research project are: (1) Review and identify the effect of confinement of narrow baseplates or reaction area on screw anchors breakout resistance. (2) Determine the effect of anchor groups and configurations on the anchor breakout resistance. (3) Determine the failure mechanism and appropriate confinement modification factor of screw anchors used in various applications. (4) Determine the screw anchors' performance under cyclic loads. (5) Develop new Florida Department of Transportation (FDOT) Structures Design Guidelines criteria for screw anchors with confinement effects. (6) Develop modified FDOT Structures Design Guidelines criteria for adhesive anchors with confinement effects if necessary.
