The paper presents a recently developed concept for the transmission of vertical loads between columns in point-supported timber slab systems. The concept consists of a specially milled beech LVL element inserted into the end of a GLT column, thus allowing to receive concentrated loads from an also specially milled LVL pin element. Under axial compression the LVL insert proved being able to redistribute the compression stresses effectively before transferring the stresses to the lower GLT column. This paper investigates the rotational stiffness of this concept, both numerically and experimentally with two manufactured specimens. For the studied geometry the obtained rotational stiffness was 3.4×102kNm/rad, being in good agreement with the finite element simulations. Relevant aspects of the robotic manufacturing relating to the tight tolerances needed are discussed.
