Abstract
The system effect of continuous connected, parallel members of spruce (picea Abies) has been the
topic of the current research work. First, emphasis was taken on overview of the system effect
supported by literature study and current national and international regulations. Second step was to
proof the system behaviour by testing samples of doubled and fourfold finger jointed structural
lumber (KVH®) as rigid connected systems in tension and bending. The reduced scatter of strength
and stiffness was objected which resulted in an increase of the 5 % quantil of MOR. Emphasis was
taken on statistical evaluation to define best fitted model to represent the data sets of the samples. In
addition bending tests of horizontal arranged 2x2 and 2x3 structures named as 'Balkenbinder' (BB)
were carried out with two different cross sections of the single components KVH®, 60/200 mm and
80/160 mm. The results obviously reflect the interaction of system effects and size effects
