Abstract:

The AASHTO specification does not specify the analysis method for base-plate design of span-wire traffic signal poles. The study reported here consisted of full-scale testing and finite element analysis of a number of existing signal poles to examine their behavior and evaluate their structural adequacy. A simplified analysis method has been developed because present procedures were found to be unreliable. This method is consistent with the working stress design concept in the current code. It decomposes the base plate into three elementary components corresponding to three critical regions of maximum stress. The subsequent analyses become straightforward on the basis of these modelings, with the assistance of empirically determined coefficients to reach equivalent section capacities with respect to critical stresses. Hand calculation is adequate for applications of this method in routine design.
