Analysis of Nailed Joints with Dissimilar Members

In order to predict the slope of the load-slip curve of two-member nailed wood joints under lateral load, a theoretical method of analysis is derived based on the theory of beams on elastic foundations. The method derived allows analysis of joints where the members are dissimilar in properties and thickness. It also accounts for nails of different sizes and materials, and for wood of different species by incorporating a foundation modulus determined from an elastic bearing constant proportional to the wood density. Values of the elastic bearing constant are presented for various types of joints. Experimental verification of the theoretical expressions are presented.
