Abstract
In this paper, experimental results on specimens with bolted joints are compared with the analysis of the generalized theory of a beam on an elastic foundation. The above specimens have the different five conditions : (1) execution method, (2) thickness of infilled epoxy, (3), (4) strength and thickness of side members, (5) number of bolts. As the results of the examination, a numerical analysis based on the above theory is applied to approximate the nonlinear load-slip relationship of bolted wood-joints with a steel central member filled with epoxy.
