The joist shall have as minimum a width = length of steel dowel.

For beams with a slope β the capacities shall be multiply with the factor.

β	0°	15°	30°	45°
factor	1.0	0.95	0.9	0.85

R_2,k capacities are calculated as R_2,k = R_1,k x (nb of dowels - 1) / (nb of dowels).

The top dowel is not considered for the uplift capacities as it is placed in an open hole.
