都是高強度螺栓，兩者區(qū)別如下：
They are high-strength bolts, and the differences are as follows:
一、承載能力不同
1、 Different bearing capacity
1、摩擦性高強螺栓：以板層間出現(xiàn)滑動作為承載能力極限狀態(tài)。
1. Friction high-strength bolt: take the sliding between plates as the limit state of bearing capacity.
2、扭剪型高強螺栓：以板層間出現(xiàn)滑動作為正常使用極限狀態(tài)，而以連接破壞作為承載能力極限狀態(tài)。
2. Torsional shear type high-strength bolt: take the sliding between plate layers as the normal service limit state, and the connection failure as the bearing capacity limit state.
二、應用位置不同
2、 Different application locations
1、摩擦性高強螺栓：不能充分發(fā)揮螺栓的潛能。在實際應用中，對十分重要的結構或承受動力荷載的結構，尤其是荷載引起反向應力時，應該用摩擦型高強螺拴，此時可把未發(fā)揮的螺栓潛能作為儲備。
1. Friction high strength bolt: it can not give full play to the potential of bolt. In practical application, friction type high-strength bolts should be used for very important structures or structures bearing dynamic loads, especially when the load causes reverse stress. At this time, the untapped bolt potential can be used as a safety reserve.
2、扭剪型高強螺栓：除摩擦性高強螺栓以外的地方應采用承壓型高強螺栓連接以降低造價。
2. Torsional shear high-strength bolt: pressure bearing high-strength bolt shall be used for connection except friction high-strength bolt to reduce the cost.
三、使用方式不同
3、 Different ways of use
1、摩擦性高強螺栓：限單次使用，用于連接，不能重復使用。
1. Friction high-strength bolt: only for single use, for connection, and can not be reused.
2、扭剪型高強螺栓：必 須先初擰后終擰，初擰高強螺栓需用沖擊型電動扳手或扭矩可調電動扳手；而終擰高強螺栓有嚴格的要求，終擰扭剪型高強螺栓必 須用扭剪型電動扳手，終擰扭矩型高強螺栓必 須用扭矩型電動扳手。
2. Torsional shear high-strength bolt: initial tightening must be followed by final tightening. Impact electric wrench or torque adjustable electric wrench is required for initial tightening of high-strength bolt; The final tightening of high-strength bolts has strict requirements. The final tightening of torsional shear high-strength bolts must use torsional shear electric wrench, and the final tightening of torque high-strength bolts must use torque electric wrench.
