• Abstract:
  This report presents a series of design charts which allow an entirely graphical procedure to be followed in selecting the proper size of drilled shaft foundation for standard Texas Highway Department signs. The procedure uses a boring log of Texas Highway Department cone penetrometer measurements and a graphical overlay-slide device which was developed in this project to determine the soil shear strength parameters, c and 0. These data are used to select one of five typical soil types which span the range of soil properties normally encountered and this determines the footing design chart to use. The footing is sized to carry the moment for which the sign support column is designed.
