Design Example 1. Cantilevered Overhead Sign Support - Truss with Post Problem statement: Location: I-85 Atlanta, GA. Design a structure to Support a sign 22 ft. long and 11 ft. high. The distance from the center of the upright to the center of the sign is 24 ft. The distance from the base of the post to the center of the sign is 23 ft. and no walkway is included. Use API-5L-X52 round steel pipe (Fy=52 ksi) for the main structure members and ASTM. A-53 Grade B pipe for the secondary members. Use AASHTO M314-90 Grade 55. anchor bolts. The structure would cross a lifeline travelway should it collapse. Reference:E:\BT\Projects\ nchrp 10-80\Examples\Release\ (R). Several commonly-used functions are stored in a separate include file that is used in multiple Example problems. These include functions to determine Cd and resistance values for flexure, shear, and torsion for common steel shapes.
