1.钢结构螺栓与普通螺栓不同。
1. Steel structure bolts are different from ordinary bolts.
钢结构扭剪螺栓一般用于连接。 常用的M16-M30。 超大型钢结构扭剪螺栓的作用不稳定，应慎用。
Torsional shear bolts of steel structures are generally used for connection. Commonly used m16-m30. The torsional shear bolt of super large steel structure is unstable and should be used with caution.
2.螺栓连接建筑结构的主要构件一般用于连接钢结构的扭剪螺栓。
2. The main components of bolted building structures are generally used to connect torsional shear bolts of steel structures.
3.一般螺栓可以重复使用，但钢结构扭剪螺栓不能重复使用。
3. General bolts can be reused, but steel structure torsional shear bolts cannot be reused.
4.钢结构螺栓采用高强度钢45钢8.8s、20MmTiB10.9S。它们是预应力螺栓。它们与扭矩扳手冲突并施加预应力。压力式螺钉一般采用普通钢Q235由梅花头螺栓制成拧紧。
4. High strength steel 45 steel 8.8s and 20mmtib10.9s are used for steel structure bolts. They are prestressed bolts. They collide with the torque wrench and apply prestress. Pressure type screws are generally made of ordinary steel Q235 and tightened with Torx head bolts.
5.一般螺栓一般为4.4、4.8、5.6、8.8。 钢结构扭剪螺栓一般为8.8和10.9，大部分为10.9。
5. General bolts are generally 4.4, 4.8, 5.6 and 8.8. Torsional shear bolts of steel structures are generally 8.8 and 10.9, most of which are 10.9.
6.一般螺栓孔不一定比钢结构扭剪螺栓大。 其实普通的螺栓孔比较小。
6. Generally, the bolt hole is not necessarily larger than the torsional shear bolt of steel structure. In fact, ordinary bolt holes are relatively small.
7.一般A、B级螺栓的螺孔一般只比螺栓大0.3-0.5mm。 C级螺丝孔一般比螺栓大1.0-1.5mm。
7. Generally, the screw hole of Grade A and B bolts is only 0.3-0.5mm larger than the bolt. Class C screw holes are generally 1.0-1.5mm larger than bolts.
8.干涉钢结构扭剪螺栓承受干涉传递载荷，因此螺钉与螺孔的差值可达1.5-2.0mm
8. The torsional shear bolt of interference steel structure bears the interference transmission load, so the difference between the screw and the screw hole can reach 1.5-2.0mm
9.压力式钢结构扭剪螺栓的标准传动特性是保证在正常使用过程中剪力不超过阻力，阻力式钢结构扭剪螺栓也是如此。
9. The standard transmission characteristic of the pressure steel structure torsional shear bolt is to ensure that the shear force does not exceed the resistance during normal use, and so does the resistance steel structure torsional shear bolt.
再次加载荷时，连接板之间的相对滑动取决于螺钉的剪力和孔壁的压力，螺栓与螺钉孔的差值略小，这是1.0-1.5mm。
When the load is loaded again, the relative sliding between the connecting plates depends on the shear force of the screw and the pressure of the hole wall. The difference between the bolt and the screw hole is slightly smaller, which is 1.0-1.5mm.
