This report presents an integrated model for design of framed timber structures with dowel-type fastener connections.
Design of dowel-type fastener connections in framed timber
structures usually involves a two-step analysis: determination of the
distribution of the sectional forces, an design of the eccentrically
loaded connections. This report presents an integrated model for design
of framed timber structures with dowel-type fastener connections.
finite element approach has been adopted. An element has been developed
for modelling a plane group of dowel-type fasteners, taking due account
of the material and geometrical non-linearities, and two different
elements have been developed for modelling gap closure and contact
pressure. All elements developed are compatible with conventional beam
elements. An arc-length technique has been adopted for solving the
non-linear equilibrium equations in order to take full account of
strain softening effects.
