The paper shows the calculation and reliability assessment of bolted connections subjected to unequal double shear with thick plates as outer members and inner timber member. This situation can occur very often during the designing of the timber structure bolt connection. Bolted connections subjected to unequal double shear are not described in present European standards where there is described only calculation and reliability of timber structure bolt connection subjected to double equal shears. So structure engineers have no rules which help them during a designing process when they are confronted with this case. The concrete example for the case of unequal shears is calculated and explained.
