Abstract:

A socketed foundation was designed and evaluated for use with the Midwest Weak Post (MWP), Version 1. ; Dynamic component testing was conducted on five different design configurations with varying embedment ; depths, steel reinforcement, and soil conditions. The low strength of the MWPs limited the force transferred into ; the foundations and prevented damage in the form of concrete cracking or fracture. Additionally, the lateral ; movements of the socketed foundations were all within the 1-in. (25-mm) limit established to ensure reuse of the ; foundations without resetting. The selected design consisted of a 12-in. (305-mm) diameter concrete shaft ; reinforced with four vertical bars and transverse hoop steel spaced at 6½ in. (165 mm) on center. A 4-in. x 3-in. ; x ¼-in. (102-mm x 76-mm x 6-mm) steel tube socket was placed in the middle of the shaft. Finally, guidelines ; were given for the length, or embedment depth, of the foundation based on surrounding soil conditions and risk ; of frost heave.
