Experimental and analytical achievements on the bearing stiffness and strength of wood in the above paper are discussed about the following items: 1) The proposed formula for bearing stiffness is based on an improper model of stress distribution. 2) The equation for calculating local stiffness in the vicinity of the contact region seems improper. 3) The bearing stiffness calculated from the proposed formula shows improper relations with bearing width as well as specimen height. 4) The size effect in bearing strength seems illogical.
