“…In simulating different geometries and stiffnesses, he concluded that the deflection-based load-sharing factor varied from 8 to 40 percent depending on the ratio of rafter to batten stiffness and rafter stiffness of the rafter and load. The distributing element was also apparent in Thornburn's (1962) study. Thornburn gave no information about the stiffness of the rafters, but the relative stiffness of the 3/8-in.…”

The first report of a three-part series that covers results of a full-scale roof assemblies research program. The focus of this report is the structural performance of truss assemblies comprising trusses with abnormally high stiffness variability and critical joint strength. Results discussed include properties of truss members and connections. individual truss stiffness and strength. and the structural performance of two full-scale truss roof assemblies. Findings support the use of linear models to predict the behavior of trusses used in residential roof assemblies. linear superposition models to characterize assembly load disbursement. and use of a load sharing increase factor to adjust individual truss load capacity when used in a repetitive member assembly.

“…There is one feature in this evaluation that warrants consideration when developing a test method for full-scale prototype testing. The use of a whiffletree assembly to transfer the load from loading devices such as a hydraulic ram to the surface of the strucure is cited in several other reports [18] , [44] .…”

As part of a comprehensive research program concerned with the structural testing of building components, conducted for the U. S. Department of Housing and Urban Development (HUD) , a search for information was conducted. This search was undertaken in order to document existing information pertaining to structural testing of wall, floor and roof assemblies. Various information sources were consulted to trace the evolution of structural testing of building construction from the 1930 's to the present time. This task was a prerequisite to defining the state-of-the-art and to identifying the test areas requiring fundamental research.
