Am. Tarabia et F. Kamiya, MODELING OF MECHANICAL WOOD JOINTS SUBJECTED TO CYCLIC AND MONOTONIC LOADINGS, Mokuzai Gakkaishi, 42(12), 1996, pp. 1188-1194
An analytical model based on the finite element method was developed t
o analyze wood joints having mechanical fasteners such as nails, bolts
, and drift-pins. Nonlinear geometric properties, due to the deformati
ons of the different components as well as the interactions between th
e wood and the fasteners, were included. Material nonlinearities becau
se of the yielding of fasteners and the crushing of wood under compres
sive loadings were considered in the analysis. Friction, due to the wo
od to fasteners interactions, was incorporated into the model. For eve
ry load step, the total stiffness matrix was determined and updated fo
r every change until equilibrium was achieved. The proposed model show
ed excellent correlation with experimental data. The model is suitable
for wood connections with different types of mechanical fasteners and
can be a basis for providing hysteretic design models for different j
oint types.
