Abstract
This paper is focused on the suitability of estimation of theoretical methods of wooden scarf joint bonded with PU adhesive loading capacity determination. Loading capacity of selected joint was experimentally determined for several wooden materials and bevel angles from 0° to 90°. Theoretical dependencies by using two different methods for selected joints were calculated from values for 0° and 90° and results compared. The first method was based on tangential on normal stress dependency substitution by ellipse. The second one was based on joint surface virtual division into 2 sections. Normal shear stress was applied on the first and the second sections. Results of the experiment showed that selected methods can be used for joints from 0° to approx. 70° of bevel angle with acceptable accuracy
