SPREADSHEET IMPLEMENTATION OF A SIMPLIFIED PROCEDURE FOR DESIGN OF END-PLATES AND BASE-PLATES OF CANTILEVERED TRAFFIC STRUCTURES

Special Report 131 ("A Simplified Design Procedure for End-Plates and Base-Plates of Cantilevered Traffic Structures," published by the Transportation Research and Development Bureau, New York State Department of Transportation, 1999) proposed a procedure for design of end-plates and base-plates of sign, signal, and light cantilevered traffic structures, and also for base-plates of span-wire-mounted traffic signal structures. The procedure was based on beam-and-plate bending and torsion theories, and is intended for routine application by practicing engineers when designing plates of square configurations. Plate thicknesses and stresses obtained using this procedure compared well with those estimated using finite element analysis, and also supported earlier conclusions reached through physical testing. In all, 35 base-plates from five major manufacturers of traffic poles used in New York State were analyzed in the study and a spreadsheet program implementing the procedure was developed as an efficient tool for engineers designing these items. Using this tool will not only expedite the design process, but also facilitate optimizing plate sizes, because various design alternatives can be easily investigated and the optimal alternative rationally selected. This report summarizes the theory behind this program and presents complete documentation of its algorithm, features, limitations, and usage. The report also includes two design examples, to illustrate the program application and serve as a reference for future users.
