The main difference between high strength bolt connection and ordinary bolt connection is: 1. When the common bolt is connected in the shear, the shear force of the bolt is depended on the bolt and the shear. When the screw is tightened, the pretension of the bolt is very small, and the influence can be ignored. 2. In addition to the high strength of the material, the high strength bolt tightens the bolt and exerts a large pretension, which causes the tension between the contact surfaces of the connected plates, so there is a lot of friction between the plate and the plate.
