Title:Performance of Four Raised-Heel or Cntilevered Wood roof Truss Designs
Author(s):Percival, Donald H.; Denny, John M.

Abstract:With the ever-increasing concern over energy costs, home owners are demanding fully-insulated structures, including the requirement for a minimum R-value of 30 in the ceiling. This will usually require at least 12 inches in added height in the attic above the exterior walls of the house. Two approaches are used to obtain this added height; 1) a cantilevered truss, or 2) a raised-heel truss. This report covers the results of testing four different heel configurations typical of those used in residential roof truss construction. These test results are intended to verify the cantilever design procedure proposed by the Truss Plate Institute (TPI). The study was done in two phases. The first was sponsored and funded in part by the Cantilever Committee of TPI (John Denny, Chairman), and the second by Lumbermate Company of St. Louis, Missouri, and the Small Homes Council Building Research Council (SHC-BRC) of the University of Illinois at Urbana-Champaign. The tests were conducted at the hydraulic test facility of the SHC-BRC.
