About this file
This is a structural design analysis document prepared by the Kentucky Department of Transportation, District 5, for an overheight detection signal support structure located in Louisville, Jefferson County. The project involves the design and analysis of a 21.5-foot vertical pole (Pole A) with two mast arms extending 35 feet in length at a height of 19 feet, each measuring 102.3 inches long by 36 inches wide by 2.3 inches thick with a weight of 500 pounds. The analysis was conducted using AASHTO 6th Edition (2013) design standards and was created on July 22, 2021, by Ted Swansegar of the Kentucky Transportation Cabinet. The document includes calculations for wind loads with a basic wind speed of 90 miles per hour, an importance factor of 0.87, and a gust effect factor of 1.14.
The design analysis reveals maximum pole loads of 5,542.65 pounds axial force, 1,610.98 pounds shear force, and a calculated moment of 71.49 kip-feet with zero torsion. The foundation design specifies a 36-inch diameter foundation with 12.5 feet of soil and 6.0 feet of rock depth, with a total volume of 3.3 cubic yards of soil and 1.6 cubic yards of rock excavation. Vertical reinforcement consists of #8 bars totaling 13 bars with #4 ties at 12-inch pitch. The document includes a professional disclaimer from Florence and Hutcheson, Inc., indicating that all calculations and results are subject to examination and verification by qualified personnel before implementation.
