1.鋼結構螺栓與普通螺栓不同。
1. Steel structure bolts are different from ordinary bolts.
鋼結構扭剪螺栓一般用于連接。 常用的M16-M30。 超大型鋼結構扭剪螺栓的作用不穩定，應慎用。
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.螺栓連接建筑結構的主要構件一般用于連接鋼結構的扭剪螺栓。
2. The main components of bolted building structures are generally used to connect torsional shear bolts of steel structures.
3.一般螺栓可以重復使用，但鋼結構扭剪螺栓不能重復使用。
3. General bolts can be reused, but steel structure torsional shear bolts cannot be reused.
4.鋼結構螺栓采用高強度鋼45鋼8.8s、20MmTiB10.9S。它們是預應力螺栓。它們與扭矩扳手沖突并施加預應力。壓力式螺釘一般采用普通鋼Q235由梅花頭螺栓制成擰緊。
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.
5.一般螺栓一般為4.4、4.8、5.6、8.8。 鋼結構扭剪螺栓一般為8.8和10.9，大部分為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鋼結構扭剪螺栓大。 其實普通的螺栓孔比較小。
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級螺栓的螺孔一般只比螺栓大0.3-0.5mm。 C級螺絲孔一般比螺栓大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.干涉鋼結構扭剪螺栓承受干涉傳遞載荷，因此螺釘與螺孔的差值可達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.壓力式鋼結構扭剪螺栓的標準傳動特性是保證在正常使用過程中剪力不超過阻力，阻力式鋼結構扭剪螺栓也是如此。
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.
再次加載荷時，連接板之間的相對滑動取決于螺釘的剪力和孔壁的壓力，螺栓與螺釘孔的差值略小，這是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.
