Lateral Resistance Capacities of Particleboard-To-Metal Screwed Connections

Abstract

A load-deformation curve was divided into three stages for investigating the lateral resistance capacity of a metal-to-particleboard screwed connection. Four models were developed for predicting the lateral resistance of three stages which were based on Johansen yield theory. Bearing strength, an important parameter in the calculation, was considering non-uniform along with the thickness direction. One important assumption in the calculation was considering if the bearing strength was uniform or non-uniform along the thickness direction. The analytical and experimental results confirm that a non-uniform bearing assumption along the thickness direction was more efficient than the uniform assumption. The x-ray and withdrawal with angle testing indicated no obvious participating axial load. The lateral resistance should not contribute to increasing lateral resistance.
