Abstract
"This report covers the testing of a 20'-0"", 4/12 slope king-post truss design using 1 1/2-inch lumber with 3/8-inch nail-glued plywood gusset and splice plates. The program was a cooperative investigation between the Small Homes Council-Building Research Council, University of Illinois at Urbana- Champaign, and GBH-Way Homes, Inc., of Walnut, illinois. The study evolved primarily from the recent changes in standard lumber sizes. Code bodies, lending agencies, designers, etc., are among those who have been requiring substantiating performance data on truss designs originally produced for 1 5/8-inch lumber and now fabricated with 1 1/2- inch lumber. The graphical methods of analysis are unreliable in calculating stresses in the nail-glued truss. The combined stresses, due to secondary bending caused by the extreme rigidity of the nail-glued joint, are not considered in graphical methods of analysis therefore full- scale testing is generally accepted as a means of determining deflection and load at failure characteristics. The objectives of the program therefore included full-scale load tests to obtain both deflection data at design load and load-to-failure information on six randomly-selected trusses representative of those contemplated for the construction of houses by the sponsor. The tests were conducted on the hydraulic test floor of the SHC- BRC, University of Illinois (2)."
