The design of bolted wood joints has, to date, been
primarily based on empirical work. Much of this has been
on single bolted joints. The extrapolation of this data to
cover multiple bolted and large diameter bolted joints is
questionable. There appears to be a lack of basic
understanding of...
Traditionally, bolted joints have been designed to
carry unidirectional loads. We have little knowledge about
the effects of combined loading on the failure characteristics
of joints with more than one bolt. In this thesis,
two techniques are presented which enable such joints to be
evaluated when they are subjected to...
Nailed joints between sheathing and framing in light-frame
wood buildings play a vital role in assuring structural
safety by providing the stiffness needed to transfer the forces
among the building components and the medium of energy
dissipation during severe earthquakes and wind storms. However,
the exact nature of load transfer...
To apply accurate procedures of structural analysis
that are now available, the behavior of nailed joints in
light-frame wood buildings under long-term loads needs to
be studied. Such a behavior can best be evaluated by
testing specimens under constant loads, which requires
relatively simple testing arrangements. To provide for a...
To make low grade lumber into high-valued products, finger-jointing is a widely
used method in the timber industry. In certain situations, chip-out occurs degrading the
quality of the joint. To better understand the machining process, a beam-type
dynamometer based on strain gages was designed to analyze the dynamic cutting forces...
Ever since composite laminate technology was introduced into the aerospace and automotive industry, there has been a need to fully understand the damage progression experienced by composite laminated plates in the presence of a notch. While numerous research studies have been conducted on this matter when subjected to in-plane loads,...
