• Abstract:
  A comprehensive study was conducted on mechanical analysis of stand-off anchor bolt connections with uneven stand-off distances. A new technique is introduced to calculate the resistive forces provided by each anchor bolt in the group in response to acting fatigue-level loads on the superstructure. The technique is able to accurately capture the resistive forces that are otherwise unaccounted for using current design and analysis methods, as well as codified provisions. The technique comprehensive, and is applicable for any standoff anchor bolt connection with even and uneven stand-off distances, as well as differing anchor bolt size and spacing. The study evaluated connections with these conditions using the analytical technique and numerical finite element analysis, and further validated from experimental field data collected on a stand-off anchor bolt connection with uneven standoff distances that was used to support a cantilever-type highway overhead sign support structure.
