Dowel timber connections with two shear planes

The paper presents the main results of an experimental research on timber-to-timber dowel connections with 2 shear planes loaded parallel-to-the-grain. The study has considered specimens with single dowel connection (of 2 different diameters, 12 and 20 mm) and with different thickness of side timber elements.

The capacity of each dowel per shear plane can be calculated as :(1) F v, R k = m i n f h, 1, k t 1 d f h, 1, k t 1 d 2 + 4 M y, R k f h, 1, k d t 1 2-1 2.3 M y, R k f h, 1, k d. Where. F v, R k is the characteristic load-carrying capacity of per steel dowel per shear plane. f h, 1, k is the characteristic embedment strength of the side member. t 1 is the thickness of the side member PERFORMANCE OF MORTISE AND TENON shoulder once a bending moment is applied to a single dowel connection. It is acting at a lever-arm from the effective centre of rotation to the dowel centre line. The effective centre of rotation is at the corner of the tenon shoulder located at B (Figure 1), creating an effectively solid hinge point [16]. d 1 shear capacity of dowels - Mechanical engineering general Jan 05, 2004 · That is why dowels are tight tolerance and bolts/screws are loose tolerance. As for shear capacity, here is the general formula: = F/A where = shear stress acting on dowel F = applied force A = dowel cross-sectional area If dowel yielding is the allowable failure mode, then: < Y where Y = dowel material shear yield strength Y = 0.577 Y where
