Flange and screwed joint
maintenance are practically eliminated.
It was concluded that the general formula that is used to predict the two-pin bending moment resistance of a dowel joint as a function of a single dowel could also be used to predict the moment resistance of the same type of screwed joint.
This current study was carried out to compare withdrawal strength and bending moment capacities of T-type end-to-side grain screwed joints constructed of three different wood species and three different screw sizes.
As a result, it was concluded that the bending moment resistance of screwed joints was affected by the ultimate direct withdrawal strength of a single screw.
In the screwed joints, depth of penetration of the screws in the edge was 32 mm.
In the chair frames constructed with screwed joints, the attachment of side frames to the top, back, and front rails was accomplished with a through bolt and dowel nut.
In general, glued-doweled and screwed joints showed different mechanical behaviors.
