Walls of the mortises
were thoroughly coated with a 42 percent solids content aliphatic resin adhesive.
Tests were conducted to determine the effect of cross pinning the tenons of round mortise
and tenon joints on the bending moment capacity of the joints.
In contrast, failures associated with mortise
or tenon failure produced an abrupt, brittle response, as a result of perpendicular-to-grain tensile as well as shear stresses.
As the separation between the crossed mortises
increased, however, leg strength increased substantially.
Initially, background information is needed concerning the difficulties encountered in cutting round tenons and mortises
of a size suitable for use with small-diameter roundwood, the ease of assembly with round mortise
and tenon frame construction, and the integrity of the assembled frame.
Severe torn grain and crushing were present on the transverse face of mortises
In form and function, these joints are equivalent to corresponding mortise
and tenon or multiple mortise
and tenon joints.
Tests were conducted to determine the axial load capacities of knee braces suitable for use in light timber frames constructed with round mortise
and tenon joints.
The distribution and shape of the boundary layer can be influenced by the change of air flow form the mortise
which affects also the parameters of heat transfer.
This diameter was chosen because it was estimated that smaller diameter tenons would lack sufficient moment capacity, whereas mortises
for larger diameter tenons would unduly weaken the legs.
loose) tenon is then inserted into the pair of mortises
to join the two parts.
The purpose of the study was to determine the end-wall load capacities, behavior, and modes of failure of simulated tie beam mortises
loaded parallel to the grain in double shear.
