• Abstract:
  An updated AASHTO LRFD Bridge Design Specification introduces a new provision for the design of anchors that borrows from the American Concrete Institute Building Code Requirements for Structural Concrete (ACI 318-14). Unfortunately, the ACI 318-14 adhesive anchor design provisions are very conservative by not taking the compressive confinement effect into consideration. The primary objectives of the Florida DOT sponsored research project BDV28 977-06 were to determine the confinement effect of a narrow baseplate on adhesive anchor breakout resistance and develop a new confinement modification factor. Results indicate that the compression confinement from the baseplate significantly increases the concrete breakout resistance. A new confinement modification factor has been developed to address the increase in concrete breakout resistance.
