The high-strength bolted joint using HF-splice plates which are high strength and hardness splice plates with sawtooth-shaped projections on their friction surfaces realize a friction coefficient of over 1.2. For these bolted joints, it is xpected that increased force transfer capability greatly affects the resistance of the net section failure. In this paper, therefore, the net section strength and deformation capacity are further studied theoretically and experimentally. This paper consists of two parts: The first half is to obtain the conditions that the gross section may be used instead of the net section for calculating the elastic strength, and that no slip occurs in the joints before the plastic deformation of the member develops sufficiently. To use these conditions for design, a slip coefficient at each bolt position of the joint must be definite. So the second part is to derive the equation of this slip coefficient from experiments and theoretical considerations. Through this research, the various behavioral characteristics are shown quantitatively for design purposes.
