Deflection Calculation Model for Structures with Annular Base Plates
The deflections of mast arm and light pole structures are typically calculated by assuming the structure to be fixed at the base. However, addtional rotation from the base plate and anchor bolts has been found to increase the overall deflection. The purpose of this study was to evaluate the contribution of the base plate and anchor bolts to the overall deflection (rotation) of a typical mast arm and light pole, A finite element model of the base plate system was first used to predict the deflection and overall rotation. To verify its accuracy, the results of the finite element model were compared to lab tests in which a tubular member was welded to an annular base plate that was connected to a foundation with anchor bolts. The finite element model was then used to calculate the deflections and rotations of typical Florida Department of Transportation (FDOT) base plate systems.
