Table 2 Stresses at failure compared to the strength values obtained via testing. τ is the shear stress at failure; σ_c,90 is the compressive stress perpendicular to the grain at failure; f_v is the experimentally measured shear strength parallel to the grain of the respective timber joist; f_c,90 is the experimentally measured proportional limit of the compressive strength perpendicular to the grain of the respective timber joist
